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.

A system for automatically positioning a plurality of tool-holding carriages along an elongate guide member utilizes a single drive member to move all of the carriages simultaneously. The carriages each have clutches for selectively engaging or disengaging the drive member so that the carriages can be moved relative to each other by the drive member, and can be moved simultaneously in opposite directions along the guide member if desired. The drive member is capable of moving each carriage throughout its respective maximum range of movement with a continuous motion, without any reversal of the drive member or any disengagement of the respective carriage from the drive member. Each carriage has an electrically-powered position sensor capable of transmitting different discrete signals for different positions of the carriage so that it provides absolute indications of position rather than indications which are relative to some reference position. A sealing enclosure surrounds both the drive member and the carriages, so as to prevent the entry into the enclosure of airborne particles, and likewise surrounds all fluid and electrical power conduits to the carriages. Automatic positioning of the various carriages is simplified by precisely positioning them sequentially, in an order corresponding to progressively larger distances of movement required for each carriage to reach its desired position.

A power operated tool positioner for moving a tool parallel to a tool-positioning axis has a first tool-contacting member movable parallel to the tool-positioning axis for exerting a first pushing force against the tool, and a second tool-contacting member movable transverse to the tool-positioning axis for simultaneously exerting a second pushing force against the tool perpendicular to the first pushing force to resist any tendency of the first pushing force to tilt the tool obliquely relative to the tool-positioning axis. A third tool-contacting member is preferably provided for exerting a third pushing force to push the tool in the opposite direction from the first tool-contacting member, likewise while the second tool-contacting member is simultaneously pushing against the tool. The second tool-contacting member preferably exerts its pushing force prior to the commencement of the first or third pushing force. The three tool-contacting members are preferably interconnected so as to move in unison, the second tool-contacting member being movable relative to the tool parallel to the tool-positioning axis while simultaneously exerting its second pushing force against the tool.

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.

An elongate expansible shaft for a roll core has a peripheral surface defining multiple separate elongate slots helically intertwined and oriented at a pitch angle no greater than about 30. degree. measured from a longitudinal axis. Each slot is T-shaped in cross section and contains a respective separate, elongate, resilient bladder pneumatically expandable into frictional engagement with the core. The bladder has a unitary construction with hinge portions for minimizing the loss of force due to expansion of the bladder. An air inlet fitting is inserted in one end of each bladder and is independently connected to a respective separate valve for preventing the escape of air from the bladder irrespective of the air pressure in any other bladder.
