Abstract: An automatic screen registration device for a registering a screen printing frame and method of use that includes generally (1) a print head or plurality of print heads; (2) frame or frames attached directly to the print head(s) and (3) a means for positioning a screen in the frame(s). The present invention uses a multi-point registration system that is attached to each print head of a screen printing system.
Abstract: A cart for maintaining items specifically used in the printing industry includes four upright support members disposed in pairs substantially parallel and spaced apart from one another to define the corners of a box shape having a rectangular plan view. Rectangular frame members are horizontally disposed, one spacedly above the other and connected at each one of the four respective corners to one of the four upright support members. A plurality of hanger brackets are connected to and depend from the rectangular frame members and are suitably sized and shaped to receive and retain, in a suspended, substantially vertical position accessories, tools and supplies commonly used in the printing industry.

Abstract: A device for adjustably supporting a print screen during application of emulsion includes an upright stand assembly which is adapted to permit vertical adjustment of the position of a print screen mounted on a screen frame support rack on the device. A screen frame support rack is rotatably connected to the stand assembly in such manner as to permit selective vertical rotation of the entire screen frame support rack by up to at least 180.degree. around a first axis, which first axis is substantially horizontal and extends radially, outwardly from longitudinal axis of the upright stand. The screen frame support rack is adapted to support the print screen in such a manner as to permit selective rotation of the print screen around a second axis of rotation to any angle up to at least 180.degree.

Abstract: A screen printing apparatus has simultaneously movable multiple print heads made movable by a single fluid cylinder. The apparatus also has multiple printing platens, and structure for indexing and simultaneously registering the multiple platens into printing position, as well as combined flood bar/squeegee ink applicators which are capable of simultaneously shifting of operational positions, and provide a high quality printed image on the goods printed thereby.
Abstract: A take-off device for gripping and releasing an article has a gripper heat capable of imparting a downward force to an article gripped thereof. The gripper head has a lower jaw and an upper jaw, the lower jaw being capable of moving linearly with respect to the longitudinal axis of the take-off device. The upper jaw is capable of pivotal movement below the line of linear movement of the lower jaw after the lower jaw has moved linearly to release the article gripped by the gripper head, whereby a downward force to an article gripped and released by the take-off device may be imparted.
