| 226195000 | WITH MEANS TO RETARD MATERIAL MOVEMENT (E.G., "TENSIONER") | 8 |
| 20080264995 | Buffering And Tension Control System And Method - A method of buffering and controlling the tension of a print substrate moving through a web press comprises: supporting a loop of print substrate on a movable roller, wherein translational movement of the roller is controlled by a motor; and controlling the motor to achieve a sequence of roller movements arranged to control tension of the substrate during a sequence of variations in substrate velocity during a printing cycle. | 10-30-2008 |
| 20090057364 | Sheet material tensioning apparatus - A sheet material tensioning apparatus includes frame members interconnected one with another to define a closed contour. The apparatus applies tension to sheet material by imposing a separation between frame members to expand the closed contour. Beneficially, the sheet material tensioning apparatus includes an edge-bridging mechanism, such as a spline, to span the gap between the separated frame members. The edge-bridging mechanism maintains the continuity of the edge supporting the sheet material. The sheet material apparatus may include a crossbar assembly to add rigidity to long frame members, while maintaining planar alignment even under considerable compression. | 03-05-2009 |
| 20090108045 | HIGH SPEED TICKET DISPENSER - A redemption ticket dispenser is disclosed having a ticket path defined by a series of interchangeable rollers to accommodate different width tickets, the dispenser having a pair of pinch rollers disposed at the mouth of the dispenser to pull tickets through the dispenser and out of an arcade game. The pinch rollers are mounted on a pivoting arm that is held in place by a removable tensioning member. With the tensioning member removed, the pivoting arm can be rotated out of the ticket path to allow ticket jams to be cleared without removing the dispenser from its housing. | 04-30-2009 |
| 20090120990 | Method for adjusting the web tension of a processing machine - For adjusting the web tension of a processing machine for processing a continuous material, in particular a shaftless printing press, the continuous material is subdivided into at least two web-tension sections, with one web-tension section being limited by two clamping points; the web tension is adjusted in the at least two web-tension sections when the continuous material comes to a standstill. | 05-14-2009 |
| 20090134193 | ARRANGEMENT FOR BELT CONTROL - An arrangement for handling a paper, cardboard, tissue or other fibrous-material web in a machine for producing and/or finishing the same, includes an endlessly circulating belt of high flexural rigidity which wraps around a rotatably mounted control roller with an angle of wrap, wherein at least one end of the control roller is displaceably mounted along an adjusting zone for setting the belt tension. The arrangement of the present invention provides an improved running of the belt and the lateral stress of the belt is minimized by the angle of wrap lying between 90° and 180° and the adjusting direction of the control roller lying approximately perpendicular to the bisector of the angle of wrap. | 05-28-2009 |
| 20100252604 | PINCH VALVE - A pinch valve includes a valve body having a slot which is configured to allow a web of substrate material to pass therethrough. The valve body has a sealing surface which includes a first curved portion with a first radius of curvature. A dynamic seal element is configured to engage the valve body and includes a second curved portion having a second radius of curvature which is larger than the first radius of curvature. An actuator is operable to selectively bias the dynamic seal element into and out of engagement with the valve body so that when it is biased into engagement with the valve body the web of substrate material is engaged between the sealing surfaces of the dynamic seal element and the valve body. Also disclosed is a processing system which includes the pinch valve. | 10-07-2010 |
| 20110309125 | GENERAL PURPOSE DISPENSER TO DEPLOY AND EXPAND WEB MATERIAL - A dispensing mechanism that deploys a roll of web material having slit cuts and expands it into a web with a cellular structure. This is accomplished by mounting the roll of unexpanded web material on an axle that is positioned at a first angle to a guide wheel assembly. That first angle is not perpendicular to the direction of deployment. The material moves through the guide wheel assembly longitudinally in such a way that tension is applied at a second angle to the direction of deployment. This diagonal tension causes the web material to expand and form cells. Single axle as well as multi-axle systems are disclosed. In this way, a plurality of rolls of web material may be deployed and expanded as a single unit. | 12-22-2011 |
| 20150122866 | Full contact teter dispension for controlling deployment of expandable web material - An automatic traction control system expands and deploys compact tightly wound precut paper with die cut slits. The system has an axle with a smaller diameter than the diameter of a tube over which a precut paper package is wound, providing friction free rotation. The precut paper roll rests against a spongy device at one end. The other end rubs against an adjustable cylinder assembly, providing friction that prevents paper spill and misalignment. The axle of the paper handling mechanism is set at an angle to the grab direction of an edge of the precut paper, expanding the grabbed edge and the ungrabbed edge. Grabbing is effected by a belt and two rollers applying precise controlled vertical loading obtained by a slidable and rotatable plate having the weight of a motor, gearbox and pulleys. Due to the angle set, the precut paper stretches expanding the precut paper to three dimensional shape. | 05-07-2015 |
