Abstract: A method and apparatus (10) for lining the interior surface (45) of a vessel (18) with a continuous ribbon (44) of lining material. The apparatus (10) has a cantilevered boom (21) with a guide assembly (25) secured to the unsupported end portion (24) of the boom (21). Mechanism (34-38) drives the conveyor belt (33)--from a location that is normally exterior to the vessel (18)--along the boom (21) and about a path defined by the guide assembly (25). The guide assembly (25) both turns and twists the conveyor belt (33). Turning the belt (33) causes it to encircle the boom (21), thereby extending the belt (33) radially to engage the interior surface (45) of the vessel (18). In addition, the guide assembly (25) twists the belt (33) so that the normally inner, supporting surface (46) thereon temporarily reverses positions with the normally outer, sliding surface (49).

Abstract: Metal parts are coated with one or more layers of a solvent-based adhesive using a roller coating procedure. The adhesive solution is transferred from a supply reservoir to the metal part by a natural fiber felt covered roll. The freshly coated part is then dried and the coating and drying procedure repeated until a layer of adhesive of desired thickness is built up. The use of a natural fiber felt covered roll permits uniform transfer and application of the adhesive at efficiencies above 90% (ratio of adhesive on the part to total adhesive used).

Abstract: My invention relates to the method and apparatus for printing stripe patterns on the outside surface of cylindrical objects such as glass tumblers with their axes vertical during the printing operation, the stripes being printed substantially circularly about the axis of the cylinder as the center. The cylinder being striped is supported at a printing station for free rotation about its vertical axis. A stripe printing head provided with a stripe printing roller and an ink applicator drum, both rotating about substantially vertical axes, is moved to bring the printing roller in tangential printing contact with the tumbler surface. The printing head includes an enclosed ink (or pigment) supply well adjacent a segment of the perimeter of the applicator drum and means for maintaining the supply well full from a supply reservoir.

Abstract: A "silk screen" is provided with a patterned pervious portion the dimension of which, in the direction of screen movement, is substantially less than the circumference of the cylindrical substrate. The screen is then moved beneath a squeegee through a distance which is greater than the indicated dimension of the pattern but less than the substrate circumference, the result being that a thick film of resistive material is metered onto the substrate without any overlapping or smearing. The squeegee, at the end of the screen-printing stroke, is located at an impervious portion of the screen, so that even unspindled small-diameter ceramic substrates are disengaged from the screen with no sticking or smearing. Such cylindrical substrates are solid in order to be economical, and to permit zero moisture intrusion. It is a feature of the invention that such economical solid substrates can be used, and are driven solely by screen friction so that loading, unloading and other problems are minimized.
