Shearing means operate crosswise to the blister band, in alignment with the corner zones defined by the cut out means, to separate single blister packs. The position of the cutting means and cut out means and/or the shearing means can be adjusted to produce blister packs having different sizes.

Abstract: A method and an apparatus for cutting a laminate made of a brittle material and a plastic with a cutting tool is described. The plastic is heated up, thereby lowering its viscosity, at least in the region of a predetermined cutting line. A cutting tool is placed onto the plastic side of the laminate, the loading pressure being adjustable. By moving cutting tool relative to the laminate along the predetermined cutting line, the plastic is severed; at the same time the brittle material is scored, thereby inducing a mechanical stress. If appropriate, the mechanical stress along the cutting line is subsequently increased to exceed the rupture strength of the scored brittle material. A preferred application is the cutting of thin glass or glass-ceramic/plastic laminates.

Abstract: An apparatus for cutting blocks of ice has a frame which defines a feed chute slightly larger than the uncut block of ice. Four saws are mounted to the frame in pairs. Each pair of saws includes two counter rotating, radial saw blades aligned opposite each other and extending toward one another into the feed chute of the frame.

A discharge assembly is secured to the frame to assist in removing the cut ice from the frame. The frame is mounted on a stand in an inclined position with the feed assembly higher than the discharge assembly to allow gravity feed of the ice. A gang of blades may be used with the saws in order to cut the block of ice into smaller sized blocks with one pass through the feed chute. The saw blades have carbide-tipped saw teeth to extend the amount of use between resharpening or replacement.

Abstract: A dry-wall cutting tool is described. It has a block-like configuration and is designed to slide over the edge of the drywall and to cut both sides of the drywall to the same distance from the edge and at the same time as it does so. The depth of the cut (i.e. distance from the edge of the drywall being cut) can be controllably varied considerably and it will typically be between 1/8 inch and 6 inches deep from the edge of the drywall that is being cut. The cutting tool has vertical threaded shafts upon which are mounted cutting wheels and rubber or nylon rollers, with ball bearings between the shafts and the cutting wheels and rollers. Due to its construction the twin cutting can be done quickly and with little manual effort or force.

Abstract: The invention relates to an arrangement of a plurality of holding, centering or knife jaws (7, 18) for cutting and/or stripping apparatuses for rod-like or cable-like articles (22). The jaws (7, 18) are each displaceable or pivotable in a certain direction. The end points of a line (5) which, when the jaw (7, 18) is viewed, is turned to face the article (22) define a straight line (2). The angle between the particular direction of each jaw (7, 18) and this straight line (2) is less than 90 degrees. This results in constantly changing contact points for changing diameters of the articles (22), and distributed wear of the jaws (7, 18).

Abstract: A device separates attached multiple printed circuit boards without damaging solder connections and delicate surface mounted components attached to the boards. The device comprises a pair of disc cutters positioned in opposed alignment and minimally spaced apart for providing a bifurcated cutting edge through which commonly attached sections of the printed circuit boards are conveyed while supported by a transporter. The contact pressure on the boards is limited to the commonly attached sections as they are engaged and conveyed by the cutting edge. Minimal stress and vibrations are imparted to the boards and therefore the components connected thereon with this device. The boards are thus separated while avoiding damage to the solder connections or the surface mounted components.
