摘要:
The load applied to a scoring wheel to the combined load of a first predetermined constant load and a second variable load. The second load is varied in response to changes in the scoring speed to provide a uniform scoring depth.

An apparatus for forming frangible score lines in rigid plastic sheet material. The apparatus utilizes a flat surface having a serrated edge having points and notches. The rigid plastic sheet material is laid on the flat surface. A scoring means is positioned to strike downwardly on the sheet material whereby the points of the serrated edge of the flat surface will extend into the sheet material a distance further than the notches of the serrated edge to thus form a corrugated fracturable score line in the plastic sheet material. The apparatus is useful for forming score lines in lids for drink cups intended for fast food service.
摘要:
Apparatus and a related method for its operation, for removing a cover from a microcircuit package without significant damage to the package or contamination of its contents. The apparatus includes a work table on which the package to be opened is placed, a clamping assembly for removably securing the package to the work table, and a cutter blade positioned in an operative relationship with the clamped package. Also included are adjustment controls to allow for adjustment for the width, length and depth of the cut, and control circuitry for effecting movement of the work table in a cutting stroke with respect to the cutter blade, to cut along an edge of the cover, and for automatically reversing the table movement to return it to its starting position. A vacuum system is employed to remove and contain metal fragments and thereby minimize contamination of the package.
