ABSTRACT:
A device is provided for stretching a screen secured to a screen printing roller frame. A series of wrenching stations are provided on a fixed work area. The wrenching stations include a wrench member shaped and dimensioned to mate with the end portions of the roller frame rollers so that the wrench may cause rotation of the roller. A first and second wrenching station are positioned adjacent one another at one corner of the work area and are fixed in position. A third wrenching station is positioned opposite the first wrenching station for rotating the opposing parallel roller in the roller frame at the same end as the first wrenching station. A fourth wrenching station is provided in an opposing relationship with the second wrenching station similar to the relationship between the first and third wrenching station. Actuation of the wrenching stations rotates and torques the respective rollers, stretching the screen on the roller frame. Preferably, the wrench members include an arcuate surface which defines an application area for applying a constant force to the rotate the rollers.
