Detachable print screen fabric assembly for use in a frame tensioning system

摘要

A print screen frame tensioning system, generally rectangular in shape and fabricated from extruded tubular rails, each rail of the frame having a longitudinal channel, generally circular in cross sectional area, formed in each of the tubular rails for substantially the length of the tubular rails for receipt of a tension roller, the tension roller having its entire length axially serrated in order to accept a tensioning tool at one end, the tension roller having a longitudinal groove or slot formed therein for receipt of a fabric panel and locking strip, there being a locking strip associated with each edge of a fabric panel being slidably secured to each tension roller.

主权项

1. An improved detachable screen fabric assembly for a printing screen system, said printing screen system, having a substantially rectangular frame, having a plurality of rails fixedly connected to one another; a plurality of tension rollers rotatably mounted to the plurality of rails and rotatable along a longitudinal axis, the ends of said tension rollers accepting a tensioning tool; the improvement comprising:
a longitudinal groove formed on each of said plurality of tension rollers, said longitudinal groove for receiving an edge of a detachable screen fabric therein, said detachable screen fabric having a substantially rectangular screen fabric surface having a flexible locking strip positioned on each edge thereof for insertion into said groove with said edge of said screen fabric, wherein said groove is longitudinally formed on each of said tension rollers, said groove having an entryway opening, wherein said groove is less than the length of said roller, each of said plurality of tension rollers being formed with at least one planar flat spot on its circumference in alignment with said groove for slidable insertion or removal of said lock strip and said respective edge of said detachable screen fabric from said tension roller, said groove further having a longitudinal upper slit for slidable receipt of said edge of said reinforced screen fabric.
