METHOD AND APPARATUS FOR MAKING PACKETS OF AMORPHOUS STEEL STRIP FOR TRANSFORMER CORE MANUFACTURE

This method of making packets of amorphous metal strip adapted to be wrapped about the arbor of a transformer-core-making machine comprises providing first and second composite strips, each comprising many thin layers of amorphous metal strip stacked in superposed relationship. The composite strips have leading ends that are located in initial positions (i) axially spaced from each other at the start of a packet-making operation and (ii) at opposite ends of a stacking zone where the packets are built up during a packet-making operation. The composite strips are cut to detach first sections of strip from the first composite strip and to detach second sections of strip from the second composite strip; and the detached sections are axially advanced forwardly of the respective composite strips from which they are detached into said stacking zone. The second sections are stacked in alternating relationship upon the first sections in the stacking zone. We utilize for advancing each of the first sections into the stacking zone first transport means that is moved in a first-strip forward direction during said advancing of each of the first sections and is returned to a home position in preparation for each succeeding advancing operation of a first section. For advancing each of the second sections into the stacking zone, we utilize second transport means that is moved in a second-strip forward direction during said advancing of each of the second sections and is returned to its own home position in preparation for each succeeding advancing operation of a second section. Each of the second-section advancing operations is performed concurrently with return motion of the first transport means toward its home position, and each of the first-section advancing operations is performed concurrently with return motion of the second transport means toward its home position.

SHEAR TO CUT UP TRANSVERSE FOR SHEETS LAMINEES, IN PARTICULAR FOR STRONG SHEETS

Device for cutting sheet metal and the like

In a cutting table for sheet metal and the like, the portion of the work that overhangs the table where it is cut is supported on a traveling adjustable support (9) having rollers on its upper surface. As the upper blade is brought down to cut the work progressively from the side near the pivot of the blade to the opposite side, a traveling carriage on which the traveling support is mounted is caused to move along the length of the cut so that it provides support to the work at the location where the blade is doing the cutting. The support is pivoted on an axis perpendicular to the cut so that it can adjust itself to the inclination of the upper cutting blade, the pivot being fixed on a vertically slidable member guided in the carriage. Hydraulically driven pistons enable the support to be raised or lowered with respect to the carriage. Wide cuts can thus be made without the strip that is cut off being twisted, coiled up, or otherwise deformed.

In a cutting table for sheet metal and the like, the portion of the work that overhangs the table where it is cut is supported on a traveling adjustable support (9) having rollers on its upper surface. As the upper blade is brought down to cut the work progressively from the side near the pivot of the blade to the opposite side, a traveling carriage on which the traveling support is mounted is caused to move along the length of the cut so that it provides support to the work at the location where the blade is doing the cutting. The support is pivoted on an axis perpendicular to the cut so that it can adjust itself to the inclination of the upper cutting blade, the pivot being fixed on a vertically slidable member guided in the carriage. Hydraulically driven pistons enable the support to be raised or lowered with respect to the carriage. Wide cuts can thus be made without the strip that is cut off being twisted, coiled up, or otherwise deformed.

Method and apparatus for making packets of amorphous steel strip for transformer core manufacture

This method of making packets of amorphous metal strip adapted to be wrapped about the arbor of a transformer-core-making machine comprises providing first and second composite strips, each comprising many thin layers of amorphous metal strip stacked in superposed relationship. The composite strips have leading ends that are located in initial positions (i) axially spaced from each other at the start of a packet-making operation and (ii) at opposite ends of a stacking zone where the packets are built up during a packet-making operation. The composite strips are cut to detach first sections of strip from the first composite strip and to detach second sections of strip from the second composite strip; and the detached sections are axially advanced forwardly of the respective composite strips from which they are detached into said stacking zone. The second sections are stacked in alternating relationship upon the first sections in the stacking zone. We utilize for advancing each of the first sections into the stacking zone first transport means that is moved in a first-strip forward direction during said advancing of each of the first sections and is returned to a home position in preparation for each succeeding advancing operation of a first section. For advancing each of the second sections into the stacking zone, we utilize second transport means that is moved in a second-strip forward direction during said advancing of each of the second sections and is returned to its own home position in preparation for each succeeding advancing operation of a second section. Each of the second-section advancing operations is performed concurrently with return motion of the first transport means toward its home position, and each of the first-section advancing operations is performed concurrently with return motion of the second transport means toward its home position.

Apparatus for cutting and sorting diagnostic strips

Diagnostic strips of the kind which are exposed to biological fluids such as blood or urine to detect or monitor medical conditions are cut sequentially from elongated cards by a reciprocating shear blade. The cards may be ones which exhibit defective areas that should not be included in the finished strips. Blade motion seats each newly cut strip on a movable strip carrier which abuts the blade during the cutting operation. The carrier then travels a nondefective strip to a pickup location where it is precisely positioned and picked off of the carrier for emplacement in a housing. A strip with a defective area is carried further to a discharge location where it is released into a waste receptacle. This enables more economical manufacture of diagnostic strips by efficiently making use of nondefective areas of cards that have defective areas.

Laminate cutter

A work supporting precision cutting apparatus, for example, an appropriate leg supported table for cutting high pressure laminates expressly designed for use in the cabinet industry, more precisely, laminates which have been sprayed with contact adhesive and which are expeditiously cut into strips designed and adapted to edge cabinet doors. In keeping with prevailing shop practice it has been necessary, as is known, to cut strips from a sheet of pressure laminate Formica, for example, on a support surface using a table saw. Likewise and following the sawing step it is customary procedure to spray the applicable surface of the cut strips with contact adhesive. This manner of accomplishing the result is laborious, time-consuming and perplexing. For instance, if the sheet of laminate is sprayed before stripping on a table saw, chips of laminate stick to the adhesive and virtually make the cut strips useless. An acceptable solution of the prevailing and exasperating problem invokes the use of a double shearing action which, in turn, involves a vertically liftable and lowerable cleaving blade the cutting edge of which is movable between two coplanar closely spaced fixed bed blades, there being no chips and with the result that the discardable and useless piece is freed, cut out and dropped into an accumulating or collecting bin without coming into contact with the strip to be used.

Punching tool

In a punching tool having a punch body (23), a punch driver (33) integral with the punch body, a punch head (45) disposed over the punch driver and struck by a striker (59), a punch guide (15) for guiding the punch body, a stripper plate (17) disposed under the punch guide, and a stripping spring (51) interposed between the punch guide (15) and the punch driver (33), the punching die further includes a first damping member (39) interposed between the punch guide (15) and the punch driver (33) so as to be elastically deformable within a predetermined deflection value. Owing to the presence of the first damping member (39), it is possible to reduce noise generated when the punch body (23) is returned upward by a strong urging force of the stripping spring (51) after work has been punched, thus preventing overall noise generated during punching processing.

Shearing tool for punch presses

The invention provides a punch press and shearing tool which operate to provide a series of cuts linked end-to-end for severing a work piece such as a piece of sheet metal. The shearing tool includes first and second elongated, cooperating cutting blades. Each of the blades has a pair of slidably related faces that slide against one another in a plane of reciprocation. The cutting edges are oriented at a small angle, e.g. 2° to 6°, relative to one another to sever a piece of sheet stock progressively along a line with a scissor action. An intermittent work piece advancing motor shifts the work piece toward the cutting blades and parallel to the cut when the blades are apart. Gripping members can be yieldably mounted adjacent the cutting blades to grasp and forcefully hold the work piece in place as one blade moves toward the other. Yieldable stripper members on opposite sides of the second blade engage and independently deal with the stock on opposite sides of the cut.

Cutting mechanism

Sheet-cutter having motor driven push cutter

A sheet cutter cuts a portion of a continuous sheet, discharged through a gap between a pair of moving and stationary knives respectively having arc-shaped and straight knife edges. A motor rotates a pair of rotatable, identical gear wheels engaged with each other and opposed to the moving knife and having a pair of respective link arms thereon. Each link arm has a first end connected to a peripheral position of the respective gear wheel by a pivot thereon and a second end connected to the moving knife by a pin inserted into a respective one of a pair of horizontally extending slits in the moving knife. Rotating motion of the gear wheels is transformed into a reciprocating motion of the moving knife against, and relatively to, the stationary knife, in which the second end of each link arm assumes one of two opposing positions, depending respectively upon a current one of opposite rotating directions of the respective gear wheel, such that one or the other rotating direction of the motor results in the reciprocating motion of the moving knife with a stroke either to cut the sheet completely or incompletely.
