ABSTRACT:
A printer plate locating device used in the alignment of printer plates with respect to a screen or stencil holder of a screen printing machine. The present invention is particularly useful when used in a multi-station printing machine where the printing machine sequentially moves the printer plates into a printing station to affect the printing or image transfer. The present invention consists of two securely connected rigid plates and a system of actuators. The mounting plate 1 acts as a support or structural member for the rest of the apparatus. The alignment plate, being smaller in size than the mounting plate, provides edges against which the substrate locating devices of the printer plate make contact. In operation, the present invention is fastened to the screen holder in place of a screen or stencil on the first station of the machine. The actuators are positioned relative to the printer plate such that upon energizing, the actuators propel the printer plate into contact with the alignment plate of the apparatus. Additionally, access is provided to the lockdown devices of the printer plate to enable clamping or lockdown to the machine while the actuators are energized, thus maintaining position of the printer plate relative to the screen holder.
