A method for producing a multiplicity of miniature cavities extending from a mold surface for molding a plastic product having features integrally molded with and extending from a product base, and a mold so produced. The mold cavities are formed by depositing multiple layers of plating material on a workpiece in a predetermined pattern selected to produce a desired mold cavity shape. The mold may be in the form of a roll or belt for continuous processing, or in any form for discrete injection molding. The invention is particularly applicable to the production of touch fastener products, such as those with arrays of miniature hooks.

Forming mold cavities

A method for producing a multiplicity of fastener element molding cavities extending from a mold surface, for molding a plastic product having fastener elements integrally molded with and extending from a product base, and a mold so produced. The mold cavities are formed by depositing multiple layers of plating material on a workpiece in a predetermined pattern selected to produce a desired mold cavity shape, or by depositing a thick stratum of plating material over an array of fastener elements and then removing the fastener elements to leave shaped cavities within the plating material. The mold may be in the form of a roll or belt for continuous processing, or in any form for discrete injection molding. Molds having fastener element cavities defined by rigid cast materials are also disclosed.

A sliced food product such as a cheese product or meat product having a design or figure cut or otherwise formed therein. In accordance with a preferred embodiment, the design or figure is cut entirely or substantially through the slice so that the design or figure may be removed from a surrounding peripheral portion of the slice. A method and apparatus for forming the figure or design are also disclosed. The preferred method and apparatus employ a rotary figure cutter which cuts entirely through the slice to outline a pattern or figure, and which cuts or penetrates partially through the slice to form details of the figure by embossing or indenting design components on the slice. The slice is preferably wrapped in film prior to the figure cutting operation, and the figure cutter performs its function without cutting or tearing the film wrap. The rotary figure cutter preferably comprises a pair of rotary dies between which each slice passes as the design is formed thereon.

A sheet set feeder receives a stack of offset-jogged sheet sets, including a topmost sheet set and a next-to-topmost sheet set. The feeder separates the topmost sheet set from the remainder of the stack.

An automatic wafer loading and pre-alignment system for integrated circuit wafer-mask Aligners. A belt feed track system is employed to transport wafers from a 'send' wafer storage carrier to a wafer pre-alignment station. The wafer is machanically pre-aligned with respect to the wafer chuck of the Aligner by means of a roller arm and flat-finder system. After completion of the pre-alignment process, the Aligner turntable is rotated to carry the pre-aligned wafer and chuck to the home position of the turntable and at the same time position another chuck at the pre-alignment station. If the new chuck at the pre-alignment station contains a wafer, the wafer is transported from the chuck to a 'receive' wafer storage carrier by means of a belt return track system. The feed and return wafer belt track systems have a common portion between the pre-alignment station and the respective 'send' and 'receive' wafer storage carriers. Photosensors are used to detect the presence or absence of wafers at critical locations in the loading system and at the pre-alignment station.
