Abstract: A screen printing system has multiple screen cassettes stored in a magazine and a first screen cassette is transferred from the magazine into a printing station. The preferred cassette have an inner and outer frame with the inner frame carrying a printing screen and have off-contact and traversing members for positioning the screen at a correct off-contact distance and for engagement with a track. The preferred off-contact and traversing members comprise four wheels for rolling along the track to and from a magazine. The wheels are movable relative to the frames by an adjusting shaft and nut to change the off-contact distance. A motorized pallet conveyor conveys a plurality of substrates, each of which is loaded one of a series of pallets of the conveyor, into and from the printing station and about an endless path.

Abstract: A screen printing apparatus for printing multiple impressions on a substrate carried to and from a printing station wherein the apparatus has a frame for the screen printing apparatus with at least one printing station on the frame holding the printing screen and having an image thereon for printing on the substrate. A series of pallets are used to carry a substrate into the printing station with each pallet carried by a conveyor in an endless path vertically above the central, horizontal axis while keeping the pallets substantially parallel and horizontal as they travel to and from the print station. A cassette carries individual screens with the cassettes being loaded into a storage magazine for transfer to the printing station for successive color printing on the respective substrates.

Abstract: A screen printing system has multiple screen cassettes stored in a magazine and a first screen cassette is transferred from the magazine into a printing station. A motorized pallet conveyor conveys a plurality of substrates, each of which is loaded one of a series of pallets of the conveyor, into and from the printing station and about an endless path. After printing the first image or color, the first screen cassette is returned to the magazine and a second preregistered screen cassette is brought to the printing station with a second image or color being printed on each substrate as the pallets carrying the substrates are conveyed into and from the printing station. Preferably, the substrates and pallets are maintained in a horizontal position while they travel laterally, downwardly and upwardly when moving along the endless path.
