Abstract

A subassembly initially is rigidly supported in a predetermined position within a package by both an adhesive and a mechanical interlock bond. After a work operation is performed, the adhesive is deactivated to enable the subassembly to be removed at will from the package by rupture of the readily separable mechanical bond.

Subassembly Support Package

A subassembly initially is rigidly supported in a predetermined position within a package by both an adhesive and a mechanical interlock bond. After a work operation is performed, the adhesive is deactivated to enable the subassembly to be removed at will from the package by rupture of the readily separable mechanical bond.

Multilead cable assembly 1 (Fig. 1) is held accurately positioned between adhered sheets 2,3 of cardstock, that are additionally mechanically connected by sets of crescent-shaped interlock tabs 4,5. Tabs 4,5 are created by respective sets of steeply beveled upper and lower punches 6,7 arranged at opposite sides of a slot 8 (Fig. 2) formed laterally in die 9 of punch and die unit 10. Although only one unit 10 is shown, there are preferably two units 10, one receiving within its slot 8 the right-hand long edges of superposed sheets 2,3, and the other receiving within its slot the left-hand long edges of the sheets; in such case, each unit would be movable toward each other and relative to the then stationary package 11. Then punches S move down as punches 7 concurrently move up, to thereby form the crescent-shaped tabs 4,5 that are alternately deflected downwardly (see Fig. 3) and upwardly. After the punches are retracted, the units are moved apart (see Fig. 4) to free the package 11 and concurrently effect fold- over of the tabs. To optimize fold-over, the height of slot 8 should be twice the combined thickness of sh...
