Abstract: The present invention relates to a silk-screen printing machine provided with a reciprocatingly movable squeegee arrangement adapted for printing in both directions of squeegee travel, when caused to move over a stencil placed over a material to receive print resting on a printing table. A frame incorporating the stencil is included in a frame assembly comprising an outer and an inner unit. The two units are joined together at one edge part of the printing table. Both of the units can be raised and lowered at one edge part of the printing table, while only one of the units can be raised and lowered at the other, opposing edge part of the printing table.

Abstract: A screen printing frame assembly has a rectangular main frame with laterally spaced side members, longitudinally spaced end members, and a pair of longitudinally spaced cross members extending between the side members. At least one rectangular sub-frame has laterally spaced side portions, longitudinally spaced end portions and a screen printing medium extending across the sub-frame, the screen printing medium bearing a single numeral to be printed. Each cross member has a sub-frame retaining portion engageable with a respective end portion of the sub-frame to retain the sub-frame in assembly therewith.

Abstract: A reservoir for a bobbin changer for cigarette paper or a similar paper web includes, adjacent to an inlet (15) at which the paper (10) enters the reservoir, a movable deflector (20) arranged to engage and deflect the paper as it enters the reservoir (at least while paper is being accumulated in the reservoir) and to promote folding of the paper into loops in which the paper can safely be stored in the reservoir. The deflector is preferably pivoted and is arranged to be pushed away from the inlet by the accumulating loops of paper until the deflector reaches a nearly vertical position whereupon the bunched up loops of paper drop into the reservoir.

Abstract: A multiple registration position screen mounting apparatus or printing head assembly particularly well-suited for screen printing of jersey numerals of like indicia on garments. The printing head assembly of the present invention includes a screen receiving socket portion slideably mounted for horizontal movement between a plurality of releasably fixed registration positions related to the desired placement of one and two digit numerals on athletic jerseys or the like. The printing head assembly is fixed to a conventional vertically pivoted arm mounted on a main frame adjacent to a pallet and includes a pair of horizontal guide bars upon which a carriage forming a screen receiving socket portion is slideably mounted. A registration plate is fixed to the main frame and is provided with spaced positioning slots adapted to mate with a locking pin depending from the socket portion to releasably fit the socket portion in one of the predetermined positions of travel along the guide bars.

Abstract: A stencil is provided with a slot straddled by a pair of tracks which accommodate a plurality of alphabetic/numeric plates having openings formed as characters. A mask is also insertable into the tracks to hold the plates in position and to conceal the abutting edges of the plates. The stencil is of a bendible material susceptible of being conformed to curves so that the stencil may be used in applications such as marking automobile parts with identification numbers.

Abstract: Apparatus is provided for making a permanent mark on a hard surface such as glass or the like primarily for identification purposes. A hand held gun connected to a source of compressed air is adapted to drive a stream of abrasive particles towards a stenciling head on the marking end of the gun, which is held against the surface to be marked. The head carries interchangeable stencils located in the path of the stream of abrasive particles when the gun is actuated. When the stencil head of the gun is held flat against the surface which is to be marked and the gun actuated, the stencil indicia will be formed on the surface by the action of the abrasive particles abrading and etching the surface through the stencil openings. The stencil elements are formed by photo engraving techniques to produce sharp, precise characters and the elements themselves fit snugly together when assembled to prevent leakage between adjacent elements.
