A slitting machine for removing a strip from a sheet of material. The slitting machine has a blade assembly with first and second cutting blades, and a perforating blade arranged between the first and second cutting blades. The first and second cutting blades are arranged to cut the sheet of material to define the strip and the perforating blade is arranged to perforate the sheet of material to define an end of the strip.

Methods for producing systems for the transdermal or permucosal administration of active substances and particularly transdermal therapeutic systems (TTS), wherein the active substance depots thereof have a shape that deviates from a rectangular design.

A separator disposing portion 15 is provided with a ball screw 22 and an arm 23. The arm 23 is a member which comes into contact with a holder 17 and a separator disk 18, thereby allowing them to move. The arm 23 is provided with a chuck portion 30 which is connected to a piston 29 and can be fitted to a chuck pedestal 27. The chuck portion 30 comes close to or moves away from an expansion/contraction shaft 16 in association with expansion and contraction of the piston 29. Further, the chuck portion 30 comes into contact with an outer circumference surface of the holder 17, a side surface of the holder 17 and a side surface of the separator disk 18 in association with movements of the piston 29 and a driving portion 26.

A slitting machine for threading scrap material includes first and second arbors; rotary knives disposed on each of the first and second arbors; and a pair of notching modules positioned on opposite ends of the first and second arbors. The notching modules each has a pair of shear knives for making multiple cuts in a strip of material passing through the slitting machine forming notches to enable threading of material to scrap chutes from the slitting machine.

A coil slitting tool in the form of a rotary serrator knife for use on coil slitting machines comprises a plurality of serration undulations disposed on one or more faces about the outer periphery. The rotary serrator knife tool may comprise a concentrically located bore about an inner diameter for mounting on an arbor and may further incorporate a keyway. The rotary serrator knife may be formed from an assembly comprising, a central rotary disk about which mount one or more removable inserts comprising the serration undulation portion. The one or more removable inserts may comprise serration undulations on one side or two sides and mount substantially to the perimeter of a mounting disk by use of fasteners.

Provided is a slitter device capable of quickly supplying metal bands to a cutter stand and cutting same into strips with high speed and accuracy. The metal band slitter device comprises an unwinder that unwinds a metal band wound into a coil, a cutter stand that cuts the unwound metal band into narrow width strips, and a winder that winds the cut metal band into coils. The metal band slitter device is configured to comprise a tension adjustment unit on the winder side between the unwinder and the cutter stand that provides a constant tension to the metal band and a tension separating unit on the cutter stand side that separates the constant tension on the input side and tension on the output side.
