Abstract
A system of using a metallic conveyor belt in the manufacture of can lids which prevents can lids from rotating as they are conveyed from one manufacturing station to another. Thus, the lids are not improperly cast and stamped, and as a result, discarded. A frictional augmentation area of specific depth, width, and roughness is formed upon the metallic conveyor belt top surface to prevent the can lid from rotating during manufacture. Thus, the present invention provides a simple and economically benefical improvement to the manufacturing process of can lids.
Claims16
In an apparatus for the conveyance of can lids during manufacture and stamping, wherein each of said can lids including a central portion radially adjacent, integral with and encircled by a peripheral flange, comprising:
- a metallic sheet having a top surface and a bottom surface,
- said metallic sheet having a plurality of can lid holes therethrough,
- frictional augmentation means on said metallic sheet encircling said can lid holes, said frictional augmentation means comprising a separately defined area adjacent each said can lid hole of said metallic sheet, said frictional augmentation means comprises an area engraved to a specific roughness on said sheet top surface,
- said frictional augmentation means disposed on said top surface of said metallic sheet and positioned relative to said can lid holes to locate said frictional augmentation means beneath said peripheral flange when one of said lids is concentrically disposed atop one of said can lid holes of said metallic sheet,
- whereby said frictional augmentation means provides an increased frictional force between said peripheral flange and said metallic sheet to discourage angular and radial displacement of said can lid relative to said metallic sheet.
In an apparatus for the conveyance of can lids during manufacture and stamping, wherein each of said can lids including a central portion adjacent and encircled by a peripheral flange, comprising:
- a metallic sheet having a top surface and a bottem surface,
- said metallic sheet having a plurality of can lid holes therethrough,
- frictional augmentation means on said metallic sheet encircling said can lid holes, said frictional augmentation means comprising a separately defined area adjacent each said can lid hole of said metallic sheet, said frictional augmentation comprises a concentric ring area, and said concentric ring area includes a specific width, a specific depth and a specific roughness, said specific depth being between one to three thousandths of an inch,
- said frictional augmentation means disposed on said top surface of said metallic sheet and positioned relative to said can lid holes to locate said frictional augmentation means beneath said peripheral flange when one of said lids is concentrically disposed atop one of said can lid holes of said metallic sheet,
- whereby said frictional augmentation means provides an increased frictional force between said peripheral flange and said metallic sheet to discourage angular and radial displacement of said can lid relative to said metallic sheet.
