Abstract: A strip-shaped supporting adhesive tape is joined to a ring frame, and then is stuck with a cutter blade such that the cutter blade penetrates the adhesive tape. In a state where a cutting edge of the cutter blade is brought into contact with a tape joined side of the ring frame, thereafter, the adhesive tape is cut along a contour of the ring frame while electric current is fed to each of the cutter blade and the ring frame. Herein, a sensor monitors a conduction status in real time.

Abstract: A release assembly for wire cutting apparatus. The present invention provides a release assembly for wire cutting apparatus which allows for dynamic alteration of the cut parameters. The release assembly allows for the length of the wire to be cut to be altered, allows for the biasing force to be increased or decreased to thereby reset the release assembly for a wide range of wire gauges, and allows for the stroke length to be altered to thereby either increase or decrease the cut frequency. The release assembly includes a housing having a distal end, a proximal end and a longitudinal chamber. A plunger tube is slidably disposed in the longitudinal chamber and is biased towards the proximal end by a dynamically adjustable spring mechanism. A gauge rod is mounted within the plunger tube at an adjustable axial position. In operation, the wire being pulled from the coil engages the gauge rod and pushes the gauge rod and plunger tube in the distal direction.

Abstract: A machine for cutting sheet material by means of a dinking die comprises a pair of pressure rollers through which a pack represented by a sheet material/dinking die is caused to pass by travel along a work surface transversely to a pair of rollers supported by a central frame; provision also being made for a drive unit with relative controls for rotating at least one of the rollers of the said pair alternatively in one of the two directions, wherein the said sheet material/dinking die pack are held in place by a rectangular containment frame.

Abstract: Parting device for severing a traveling elongated material into predetermined lengths, including track means, a tool slide carrying a parting tool and mounted on said track means for traveling thereon in a direction parallel to a path along which the elongated material travels past the parting device, the tool slide being displaceable at a speed in synchronism with that of the traveling elongated material as a predetermined length is being severed from the elongated material by the parting tool and being displaceable back to a starting position after the predetermined length has been severed, control means for initiating the foregoing displacements of the tool slide, reversible, flexibly yielding drive means ever actuatable for the severing operation and capable of imparting a travel speed to the tool slide greater than the synchronized speed without braking the tool slide, a member traveling at a speed continously in synchronism with the travel speed of the elongated material, and over-running clutch means i
