Yarn winding device forming cross wound package - tensioner between bobbin and piecing up device ensures correct tension after piecing up

A yarn winding device is fed from a supply with yarn which passes through pref. a main tensioner and is wond onto a take-up bobbin to provide a cross-wound package, the yarn pref. being guided onto the package by a helically grooved guide roll. When a break occurs or the trailing end of a yarn from one supply is to be joined to yarn from another supply, the ends of yarn are pieced up by a piecing up device. An auxiliary tensioning device is provided between the package and the piecing up device to tension the yarn as winding re-commences. No slack is allowed in the yarn after piecing up thereby ensuring a correct layer of yarn windings on the package.

Elastic toc plate for driving wire drawing coils

Cross winding - using rocking guide unit to describe an x path to present tensioned yarn to rotating bobbin

The rotation of the drive roller to turn the cross-wound bobbin turns a shaft fitted with a grooved pattern which causes the guide unit to rock. This rocking action causes the guiding zone to describe an X path so that the tensed yarn is moved along in alternating directions within the limits of the bobbin to form the desired cross-winding. The purpose is to give an even winding under constant tension, at speeds of 700-1000 m/min and more without breakage.

Yarn tension control - for very high speed spool winders

In a winding unit for high speed spool winding machines having a compensating roller between the feed roller and the traversing yarn guide, the movement of the compensating roller is controlled positively by the drive of the yarn traverse via a crank. A tie rod hinged on a pin adjustable in a slot in the crank is attached to a rocker arm on the free end of which the compensating roller is supported, so that the roller is lifted and lowered as the movement of the traverse reduces and increases the length of yarn between feed roller and spool.

Yarn tensioner - comprises several relatively movable parallel rods between which yarn is interlaced

The rods are suspended vertically from a common shaft along which they are freely movable as the yarn passes between the rods in a sinuous path and around an exit roller mounted on a counter-balanced lever. If the yarn tension changes the lever pivots, moving the exit roller and changing the path of the yarn through the rods. As the yarn path changes the yarn itself acts to vary the separation of the rods and so control the yarn tension to remain constant. The tensioner is used with let-off devices e.g. of warping machines.

Device and method for storing and returning yarn during the winding of conical bobbins fed with yarn at constant speed

A device and method for winding conical bobbins with yarn withdrawn at constant speed from individual spinning units, and comprising: a deflecting roller, which moves backwards and forwards by a swinging arm, which compensates for the different speeds at which the yarn is collected on the bobbin under formation wherein yarn is drawn into the storage position and is then released from this storage position, (i.e. returned). This returning operation releases the yarn from its storage position and replaces it (returns it), to its normal feed path; two proximity sensors which defines the range of swing of the yarn storage and return arm; an electronic control unit which receives an electrical signal from the proximity sensors when the arm swings stray outside the regular range to generate, an electrical control signal which activates a pressure variator which varies the pressure on a disc yarn tensioner. This changes the tension on the yarn to return the storage swing to within the regular range. If irregular swing persists, a bidirectional drive is activated to displace the contact between the bobbin and drive roller to restore the storage swing to within the regular range of values.

Sliver-calling unit, with stationary balling head, for single or double pin-field gill boxes for combing and drawing of textile fibres

774,569. Forming sliver rolls. TEMATEX SOC. R. L. Feb. 10, 1955 [Dec 18, 1954], No. 3990/55. Class 120 (1). In a sliver-balling unit of a gill box, in which the balling head is stationary and the sliver is traversed axially of the ball roll 5, the sliver delivered by the draft rollers 2 of the gill box is condensed on to a freelyrotatable guide roller 3 and then travels directly to the point of tangency of the ball 5 in a substantially rectilinear path, compensation for the variation of distance between rollers 2 and roll 5 being obtained by continuous movement of roller 3 perpendicular to its axis. Between roller 3 and roll 5 the sliver passes through a false-twist trumpet 6 carried by a guide rod 9 pivoted at one end at 10 to the arbors 4 of roller 3, and at the other end at 11 to a bracket 12 which is reciprocated along a guide 13 parallel to the axis of roll 5. Thus, the axis of trumpet 6 is always maintained in line with the direction of the sliver between roller 3 and roll 5; also, as the trumpet moves towards the ends of its traverse, roller 3, which is carried on an arm pivoted at 4<SP>11</SP>, is moved downwardly towards the position 4<SP>1</SP> so as to keep constant the distance between rollers 2 and roll 5. Trumpet 6 is rotated via gearing 14 to 17, by engagement of a gear 18 on pivot pin 11 with a stationary rack 19.
