An electrode plate slitting cutter holder includes a frame, an upper cutter holder, and a lower cutter holder. Two ends of the upper cutter holder are rotatably connected to the frame. The lower cutter holder is located below the upper cutter holder and arranged parallel to the upper cutter holder. Two ends of the lower cutter holder are rotatably connected to the frame. One of the upper cutter holder and the lower cutter holder is provided with a double-edged cutter, and another one of the upper cutter holder and the lower cutter holder is provided with a cutter groove corresponding to a position of the double-edged cutter and configured to cooperate with the double-edged cutter.

A system for converting and attaching material strips to a substrate includes a dispenser configured to advance an en elongated tape having length l1 and width w1 with l1>w1 relative to a surface of a substrate. A cutting tool cuts the elongated tape transversely along the width w1 of the tape to produce a strip having length l2 and width w2. During the cutting, a portion of the cutting Stool pushes a first surface of the strip against a gripper while cutting the tape. The gripper holds the first surface of the strip against the gripper while moving to position an opposing, second surface of the strip over the surface of the substrate. The gripper releases the strip after positioning the strip.

Methods and components produced from carbon fiber pre-impregnated composite precursor materials (pre-preg) having enhanced flowability and moldability are provided. Discontinuous cut regions are introduced into a pre-preg. A sheet of pre-preg may be contacted with a patterned surface having a plurality of non-contiguous staggered cutters, so that the contacting creates discontinuous cuts in the pre-preg. A plurality of staggered discontinuous cut regions are formed in the plurality of continuous carbon fibers that define a first plurality of carbon fibers having a first length and a second plurality of carbon fibers having a second distinct length. The patterned surface may be provided on a cutter device that is a roller or a plate having the non-contiguous staggered cutters formed or disposed thereon. The discontinuous cut regions that are formed in the pre-preg reduce stiffness and improve moldability/flowability when forming carbon fiber polymeric composites, while retaining high strength levels.

This disclosure relates generally to an assembly and process for preparing affixing tape. The disclosure also relates to an affixing assembly and process using the prepared tape. The tape can be used, for example, to affix plastic items to mailing pieces. The assemblies and processes disclosed herein provide for added throughput, less down time, higher quality of parts and production control.

A belt cutter for cutting an end portion of a belt having regularly spaced ridges on one side. The belt cutter has a main body with a slot that receives the end portion of the belt. A blade extends from the main body into the slot. A deck having one or more grooves bounds one end of the slot. The grooves receive the belt's ridges and register the belt relative to the blade. A handle is provided to pull the cutter across the width of the belt in a direction parallel to the ridges for the blade to sever the end portion from the belt and form a new butt end parallel to the ridges.

Machine to work a relatively rigid material, which comprises a plurality of operating units (20a, 20b) to work the relatively rigid material.

A cutting device and corresponding method for cutting a relatively rigid material, such as for example paper, cardboard, plastic material, composite or other. The cutting device includes a first cutting disc sharpened along its peripheral edge and rotating around a first axis of rotation. A second cutting disc, also sharpened along its peripheral edge and rotating around a first axis of rotation (X3), is disposed in front of the first cutting disc with respect to the material and is co-planar with the first cutting disc (14).

The tape can be used, for example, to affix plastic items to mailing pieces. The assemblies and processes disclosed herein provide for added throughput, less down time, higher quality of parts and production control.

A machine and a method to carry out workings on a sheet of a sufficiently rigid material is suitable to make containers. The machine includes a transverse working head guided by a first transverse guide member, one or more longitudinal working heads, each selectively positionable in a desired transverse position, guided by at least a second transverse guide member parallel to the first transverse guide member; and positioning mechanism configured to cooperate with each longitudinal working head in order to selectively position it in the desired transverse position.

A method is described in which a cutter is positioned at a cutting position according to a virtual coordinate system, media is cut at the cutting position using the cutter to create a cut, the actual location of the cut in the media is detected and the virtual coordinate system is calibrated based on an offset between the cutting position and the actual cut location.
