A conversion unit converting a first continuous web substrate into a second substrate in the form of converted blanks of predetermined length. On account of cutting tool rotation speed, the web moves at various speeds for cutting the web cut lengths and other aspects of cutting and transport process having a constant input speed. The unit includes a first motorized arrangement for producing a first run driving of the web, a sheeter having rotary tools for cutting the web into blanks, a second motorized arrangement for producing a second run driving of the substrate, the second arrangement being positioned in the immediate proximity of the sheeter, and at least one station having rotary tools for converting the blanks. A speed of rotation of the second arrangement varies during a cycle of rotation of the tools of the sheeter, comprising a phase at constant tangential speed, substantially equal to the speed of rotation of the tools of the sheeter, during which the cut is made, a speed reduction phase, during which a length of the web, dependent on the difference between the length of the blank and an extension of the periphery of the tools, is kept upstream of the second arrangement, and a speed increase phase, during which the substrate is discharged downstream of the second arrangement.

A slitter device includes an upper rotary shaft and a lower rotary shaft that are supported so as to be able to rotate. An upper slitter head that is supported by the upper rotary shaft so as to be able to rotate therewith. A lower slitter head that is supported by the lower rotary shaft so as to be able to rotate therewith and that is disposed on one side of the upper slitter head in the axial direction of the lower rotary shaft. An upper movement device that can move the upper slitter head in the axial direction of the upper rotary shaft. A lower movement device can move the lower slitter head in the axial direction of the lower rotary shaft. A control device that controls movement of the upper movement device and the lower movement device.

Provided are a slotter head, a slotter device and a box making machine comprising a cutter holder which is in a disk shape and is rotationally supported, a first cutting blade which is mounted to an outer peripheral portion of the cutter holder, a moving holder which is supported by the cutter holder movably along the circumferential direction, a second cutting blade which is mounted to an outer peripheral portion of the moving holder, a first drive device which rotationally drives the cutter holder, and a second drive device which rotationally drives the moving holder.

A cutter assembly for a printable medium comprises a cutter to cut the printable medium, a trench adjacent to the cutter, and a trench cover, the trench cover at least partially covering the trench. The trench cover is movable between a supporting configuration to support the printable medium, and an open configuration to receive portions of the printable medium in the trench. The cutter assembly comprises an elastic element for biasing the trench cover towards the supporting configuration. The cutter comprises an engaging element and the engaging element engages the trench cover to move the trench cover from the supporting configuration towards the open configuration.

A conversion unit converting a first continuous web substrate (2) into a second substrate in the form of converted blanks of predetermined length (3). On account of cutting tool rotation speed, the web (2) moves at various speeds for cutting the web cut lengths and other aspects of cutting and transport process having a constant input speed. The unit includes a first motorized arrangement (4) for producing a first run driving (F) of the web (2), a sheeter (12) having rotary tools (13, 14) for cutting the web into blanks (3), a second motorized arrangement (17) for producing a second run driving of the substrate (2, 3), the second arrangement being positioned in the immediate proximity of the sheeter (12), and at least one station (21, 22, 23) having rotary tools (26, 27, 28, 29, 32, 33) for converting the blanks (3). A speed of rotation (38, 41) of the second arrangement (17) varies during a cycle of rotation of the tools (13, 14) of the sheeter (12), comprising a phase at constant tangential speed (46), substantially equal to the speed of rotation of the tools (13, 14) of the sheeter (12), during which the cut is made, a speed reduction phase (43), during which a length of the web (2), dependent on the difference between the length of the blank (3) and an extension of the periphery of the tools (26, 27, 28, 29, 32, 33), is kept upstream of the second arrangement (17), and a speed increase phase (44), during which the substrate (2, 3) is discharged downstream of the second arrangement (17).

A cable stripper is provided which has an adjustable bushing which can be adjusted to accept a variety of differently size cables. The cable stripper is rotated around the cable to strip the insulation from a cable. The cable stripper can be attached to an existing tool to impact rotation of the cable stripper around the cable. The cable stripper includes a bushing having an axial passageway and a plurality of spaced slots which are in communication with the passageway, a plurality of cable retention blocks attached to the bushing, and a blade member mounted on the bushing, the blade member being seated within the passageway. The cable retention blocks are moveable relative to the bushing to pass through the slots and into the passageway to engage the cable mounted within the passageway. A retaining assembly is mounted on the bushing and fixes the position of the cable retention blocks relative to the bushing.

A cutting machine for cutting slices of in particular strand-shaped cutting material includes: a machine housing; a drive motor; a cutting blade, driven in rotation by the drive motor in a cutting plane, for cutting off slices; a stop plate, displaceable parallel to the cutting plane, for setting a desired slice thickness; a carriage, movable back and forth parallel to the cutting plane, having a supporting plate and a bearing wall, the supporting plate and the bearing wall forming a holding device for the cutting material, the carriage including a pivoting device for moving the supporting plate between a starting position and a pivoted-up position, the supporting plate in the starting position and in the pivoted-up position forming a right angle with the cutting plane; and a fixing plate arranged orthogonal to the supporting plate and being rigidly connected to the supporting plate, the fixing plate including a slotted link.

A slotter apparatus includes blade-attached slotter heads, receiving slotter heads, a drive device, a movement device, and a control device. The blade-attached slotter heads include slotter knives mounted on outer peripheral portions of the blade-attached slotter heads, are rotatably supported, and are disposed along a sheet transport direction. The receiving slotter heads are rotatably supported, are disposed to face the blade-attached slotter heads, and are disposed in the sheet transport direction in series. The drive device drivingly rotates the several blade-attached slotter heads and the receiving slotter heads. The movement device moves the blade-attached slotter heads and the receiving slotter heads in a rotational axis direction. The control device controls the drive device or the movement device when an adjustment mode in which each of the slotter knives is positioned at a predetermined position set in advance is selected.
