A retractable safety cover for a slitting blade edge. This cover pivots about an axis that is perpendicular to the axis of rotation of the blade edge. The cover is spring loaded in the open direction and is held in the covered orientation by a spring loaded moveable block. By retracting the moveable block the blade edge is exposed for use.

Slitter blade guard

An electronically controlled web-slitter includes dual electric motors whose functions may be controlled by an electronic controller accessed either on the chassis of the web-slitter or by way of a computer coupled to the electronic controller. Vertical and side-shift blade set-up and functions are accurately controlled. The device includes a dovetail fitting for providing structural connection of parts, and a follower engaged with said first motor for translating rotational movement into vertical motion, and multiple sensors for sensing and controlling motor positions within the device.

Web-slitter with electronic motor control

A vertically adjustable web slitter is adapted to be supported by a track of a web-slitting machine, and comprising an input port adapted to receive pressurized fluid. Also, a control assembly is adapted to controllably transmit the pressurized fluid into any one of a set of first fluid passageways. A cylinder is adapted to receive the pressurized fluid from one of the first fluid passageways. A piston, having a first end and a second end, is set into the cylinder and is adapted to be driven within the cylinder by the pressurized fluid. Further, a set of actuators that are adapted to be driven by pressurized fluid are separated by the piston and cylinder from the set of first passageways. Finally, the piston defines at least one second fluid passageway extending from the first end to the second end. A first flexible hose connects each second fluid passageway to a first fluid passageway and a second flexible hose operatively connects each second fluid passageway to one of the actuators.

Easily adjusted web slitter

A device for automatically sharpening the circular cutting edge of a disk-like blade while it is rotatably mounted in a blade cartridge is disclosed. The sharpener includes a coupling assembly adapted to matingly retain the cartridge in the same manner that it is retained in a slitter machine. A rotary drive assembly is adapted to engage with and rotate the disk-like blade while in the cartridge. A blade sharpening head is adapted to engage and sharpen the disk-like blade as the blade is being rotated by the rotary drive assembly.
