Abstract: A printing machine such as a screen printing machine having a series of pallets connected to an endless drive whereby the pallets are sequentially advanced to a printing station. The improvements reside in an arrangement in which the article support portion of the pallets are rendered readily removable to provide for interchangeability and which pallets have connected thereto guide rollers for laterally stabilizing the pallets as they advance through a printing station. An antiwhipping device is also operatively associated with the respective pallets to prohibit whipping the pallets round the ends of the endless drive, and a support arrangement is provided for supporting the pallets traveling along the lower flight of the endless drive.

Abstract: A method and apparatus for effecting the transfer printing of discrete cut-pieces of goods on a continuously rotating, drum type, transfer printer. The method and apparatus includes a rotary drum printer in which the rotary drum is reciprocally moved toward and away from a feed station in which the discrete goods are fed onto a continuous web of material having a transfer print thereon. The arrangement is such that when the drum is moved away from the feed station, the web and cut pieces thereon are indexed a corresponding amount, and when the rotating drum is moved toward the feed station, the web is held relatively motionless, thereby permitting the feeding of discrete cut-pieces thereon, permitting the drum to continue rotating to effect the transfer printing of the cut pieces previously fed into the web.

Abstract: A squeegee assembly for use on a screen printing machine which includes a squeegee holder and associated squeegee blade having a liquid filled tubular member for exerting a liquid or hydraulic pressure on the squeegee blade in a manner whereby the pressure exerted by the squeegee blade is equalized along the entire length thereof and to provide the squeegee blade with the flexibility necessary to conform to a printing surface. The assembly may also include a piston and cylinder assembly to vary the liquid pressure exerted on the squeegee blade and/or a contour bar through which the liquid pressure is transmitted to the squeegee blade.

Abstract: This disclosure is directed to a screen printing machine having an oval track or rail about which a series of pallets supporting a work piece are indexed from station to station. The arrangement is such that the pallets travelling about the oval rail are always disposed or maintained in a common plane. A printing head assembly having one or more color stations is operatively associated for movement into and out of printing relationship with one or more of the pallets as the pallets are indexed and maintained in a common plane.

Abstract: This disclosure is directed to a pallet type screen printing machine in which a pallet is indexed to a printing station when an article supported thereon is screen printed. A feed table with guides is cooperatively disposed relative to the pallet at a feed station to facilitate the accurate positioning of a work piece onto the pallet. The machine comprises an endless drive for effecting movement of one or more pallets to and from a printing station in an endless path whereby the face of the pallet is always maintained in a face up position. The pallet is formed to define a vacuum chamber which is operatively connected to a source for drawing a negative pressure thereon. A flexible coupling operatively connects the pallet to the endless drive to permit limited movement of the pallet so that the pallet may be brought into accurate registration with the printing head at the printing station.
