ABSTRACT:
A carpet or fabric screen printer has a plurality of size-adjustable screen printing rolls mounted on re-positionable heads on a long frame for the purpose of repeating a pattern in different colors. Each printing head comprises a screen printing roll on which is mounted the screen and inside of which is mounted a roller of magnetically attracted material or having a magnet unit having both North and South poles along the length thereof. The magnetic roller rolls when the head is in operation but remains in one position with respect to the screen printing roll. A continuous conveyor belt delivers the fabric sheet beneath the screen and the roller inside the screen roll. A second magnetic roller on the head beneath the conveyor belt and on the other side of the conveyor belt from the screen and the second roller also has North and South poles which are attracted by corresponding opposite poles on the first roller. Each head is mounted on side rails for selective adjustment and relocation thereon by means of adjustment dials on the head so that the distance between the heads may be changed to vary the repetition of the patterns. Each head also has other adjustments for positions horizontally and laterally with respect to the rails.
