Abstract: The invention relates to a device for the winding of a knitted material web which is being delivered from a warp knitting machine to a material roll by using an axial drive which is being regulated by sensors which measure the tension in the material web. For the purpose of winding a knitted elastic material, a spreader roller is arranged adjacent to the run-on site of the web onto the material roll and is held there with a constant gap. In order to maintain an essentially constant gap between the spreader roller and the material roll, the spreader roller undergoes a relative shifting along a radial guide.

Abstract: Laser printers are provided parallel one another so that their respective control panels face one another to define a single work station. Paper web travels from an unwind machine through the first laser printer, and instead of being provided directly to a rewind roll or the like, the paper web is adapted to move around turning bars associated with the output end of the laser printer and the input end of a second laser printer. The turning bars are oriented parallel to one another and a reversing roller results in travel of the paper web, in an upside down fashion, to a second laser printer so that it can be printed on one side in the first laser printer and on the opposite side in the second laser printer. The laser printers are also capable of printing on two individual paper webs with individual unwind and rewind machines associated with the opposite ends of the two laser printers thereby providing for conventional operation of the laser printers in an alternative mode of operation.

Abstract: A pair of freely rotatable rolls bear against the opposite edges of a moving web. Each roll is mounted with its axis generally coaxial with that of the other roll, parallel to the adjacent rollers of the web transport systems and perpendicular to the direction of web movement. A support arm for each roll is pivotally connected to a fixed support, with the pivotal axis generally parallel to that of the roll, so that the weight of the roll pivots the arms towards the vertical and causes the roll to bear against the upper surface of the web. A constant bias force may be applied to the pivotal support arm to decrease (or in some circumstances to increase) the force with which gravity causes the roll to bear against the web.

Abstract: A linear-type tape transport includes a pair of air bearings on each side of a transducer when viewed in reference to the tape transport direction. Each air bearing includes a housing and a bear member formed of a porous material. The housing and the bearing member form a plenum connectable to a pressurized air source such that air flow through the porous material creates an air cushion to support a tape medium during transport. The porous material is preferably a ceramic that is between two and fifty percent open. The bearing member has a datum face with the bearing surface thereof being planar and at a small obtuse angle to the datum face thereby to automatically urge an edge of the tape against the datum face. The housing is preferably U-shaped in cross-section with an arcuate bottom and parallel sidewalls.
