Abstract: In a web cutter where a blade is used to cut a continuous paper web into sheets, a tractor is used to move the web past the blade for cutting. The tractor operates in a start-and-stop cycle so that the web is temporarily stopped to allow the blade to lower and shear the web. The tractor accelerates in the next cycle to move another length of paper downstream from the blade. A high-speed cutter requires high acceleration of the tractor. This acceleration force causes the web to whip up uncontrollably, causing the web to break or wrinkle. To reduce the web breakage, a moving mechanism positioned upstream from the tractor and operate a second motion cycle is used to move the web toward the tractor such that a loop of paper is formed upstream of the tractor, thereby reducing the whipping action of the web.

Abstract: A gripper pulls a web off a supply downstream through upstream and downstream clamps. The upstream clamp is closed on the web and a piece is cut off its end. Then the gripper is moved back upstream to form the cut-off piece into a dependent loop while the lower part of the downstream clamp is held down and back out of the way so it does not contact the dependent loop. Once the gripper has moved upstream passed the lowered downstream clamp part, it is raised and advanced downstream to press the web against the upper downstream clamp part. Then both clamps are displaced transversely to move the web as a dependent loop transversely away.

Abstract: An apparatus for cutting sheets from an elongated workpiece is operated by first closing a pair of grippers on a workpiece leading end in an upper station and then cutting off the leading end of the workpiece to leave a sheet held in the grippers. The grippers holding the sheet are then moved downward and in an output direction to align the sheet with an output plane and pass the sheet to an output conveyor. The grippers are opened to release the cut-off sheet to the output conveyor for displacement of the sheet away in the output direction. Then the upper gripper is moved downstream in the output direction until it is out from underneath the input station and the lower gripper is moved oppositely upstream in the output direction until it is out from underneath the released sheet on the output conveyor. The upper gripper is moved upward to immediately above the upper plane and the lower gripper upward to immediately below the upper plane.

Abstract: Improvements are provided to improve an apparatus and method for processing a substantially constant velocity flow of a web of material, including a cutting mechanism and a web accumulator upstream of the cutter. The improvements include stopping the web by a side surface of the movable blade and configuring the accumulator dimensions and cutting speed to cause an appropriate level of force between the upstream severed end of the web and the blade. Several features achieve a low cutting time and modify cutting force to cut web regions with different characteristics, such as for cutting through splices. A low inertia rotary solenoid accelerates a blade through the web and against a resilient stop. The blade bounces off of the stop to its spring-biased home position. A permanent magnet or electromagnet holds the blade in the home position as solenoid current develops. These features result in reduced noise and shorter cutting time, thereby allowing an increase in web speed.

The supporter comprises supporting pins which are to be inserted in leading ends of the pipes whose trailing ends are clamped by the chuck, so that the pipes clamped at their both ends are moved intermittently a predetermined distance so as to be successively cut into the predetermined length, with their outer peripheral surfaces not being scratched or flawed due to sliding contact with clampers or other members.

Abstract: A web feeding, cutting and dispensing machine includes a pneumatic cylinder for moving a hot wire to cut measured-length sheets from web stock. A pneumatic clamp cylinder moves a clamp bar for momentarily clamping the web during cutting. Upon pressing a start button, a pneumatic control valve sequentially operates the respective cutting and clamping cylinders for quickly retracting the hot wire, while more slowly retracting the clamp. Conversely, after the next measured web length has advanced, this control valve again sequentially operates these two cylinders in reverse order for quickly clamping while slower cutting. This dual control by one valve is advantageously achieved (1) by throttling air flow in retracting the clamp cylinder relative to retracting the cut cylinder, and conversely (2) by throttling air flow in advancing the cut cylinder relative to advancing the clamp cylinder.
