Принадлежит: Lasermax Roll Systems Inc

This invention provides a system and method for aligning, feeding, trimming, slitting, rotating, cross-slitting and stacking sheets, each containing one or more discrete page images thereon that allows for greater automation of the overall process so that reduced or no manual intervention is required to generate completed book stacks or “blocks” from a stream or stack of printed sheets. Sheets are fed to a first, upstream trimming station to remove margin edges and optionally separate the sheets relative to the discrete page images. The sheets are then rotated 90 degrees and fed to a second, downstream trimming station that trims the right-angle edges and optionally separates the sheets into a final group of full-bleed pages, removing margins and gutter strips. The sheets are fed to a stacking assembly to be tacked in page order and any rejected, defective sheets or stacks are removed from the order.

A transporting device includes steering rollers, a center roller which is disposed between the steering rollers and deflection-detecting sensors that are positioned downstream from the steering rollers. When a sheet of paper has a width which is narrower than a width of a reference sheet of paper, the positional deflection of the sheet of paper is corrected by transporting the sheet of paper to a shift roller with the sheet of paper being nipped by the center roller and thrusting a forward end of the sheet of paper against a shift roller. When a sheet of paper has a width which exceeds the width of the reference sheet of paper, the positional deflection of the sheet of paper is corrected by rotating the steering rollers separately based on a detected result of the sensors with the sheet of paper being nipped by the steering rollers.

Side edge position detection processing includes adjustment of the light amount of light-emitting devices, a process of determining a threshold value for detecting the side edge position, and a process of reading out the side edge position. If a sensor is provided between a transfer roller pair and a registration roller pair as in conventional devices, sufficient processing time cannot be ensured. Therefore, the sensor is provided between the conveyance roller pair and the registration roller pair, and the light amount adjustment is executed before the registration roller pair that is being stopped for skew correction is driven. Further, the processes of determining the threshold and reading out the side edge position are executed after driving of the registration roller pair is resumed.

A self-actuating tension head for a strapping machine includes a body defining a strap path, a drive wheel, a tension wheel a fixed distance from the drive wheel and a pinch wheel. The strap path extends between the tension and pinch wheels. A first link operably connects the drive and tension wheels and defines a first pivot arm that is pivotable about the drive wheel axis of rotation. A second link operably connects the tension and pinch wheels and defines a second pivot arm that is pivotable about the pinch wheel axis and movable along the second pivot arm to move the tension wheel into and out of engagement with the pinch wheel. The first and second pivot arms define an energizing angle therebetween that decreases as the tension wheel is moved into engagement with the pinch wheel and increases as the tension wheel is moved out of engagement with the pinch wheel.

A device for dispensing active ingredient-containing or active ingredient-carrying strips, including a housing in which a coil chamber for receiving an active ingredient-containing or active ingredient-carrying band is arranged, in which a gear transmission with a driven roller for conveying the band is mounted, and in which a separating device for separating the strips from the band is arranged. A method for dispensing active ingredient-containing or active ingredient carrying strips using such a device is also disclosed. An active ingredient-containing or active ingredient-carrying band is arranged between the driven roller and the pressure roller. A shift clutch transmission having a manually actuatable trigger element is arranged upstream of the gear transmission. The driven roller can be driven in incremental strips by the shift clutch transmission. A device and method is disclosed for dispensing active ingredient-containing or active ingredient-carrying strips with a largely equal dosage are developed.
