Metal Mask Interchangeable Attachment Structure

This attachment structure permits masks to be quickly and accurately attached and detached from a mounting plate and provides lateral flexibility.

The conventional practice for mounting metal masks to insert plates in screen printing apparatus is to bond the mask to the plate with a suitable adhesive. This procedure is exacting, time consuming, and tedious. This is because the mask must be accurately positioned relative the plate and the adhesive must be given time to cure. Further, in many screen printing devices, it is desirable that the mask printing pattern be permitted limited flexibility in a direction normal to the plane of the mask to insure a tight contact between it and the substrate being screen printed. Bonding the mask to the plate does not normally provide sufficient mask flexibility.

This mask attachment structure consists of downwardly extending flanges 11 on the peripheral edges of flat metal mask 10. Flanges 11 are formed by notching the corners of mask 10 and folding over the edges. Flanges 11 are either received in grooves 12 on insert plate 14 or fold over sides 17 of plate 14. Flanges 11 accurately locate mask 10 and its associated printing aperture or pattern 15 relative to plate 14 over aperture 16. Precise location of mask 10 results because an area of contact extends along the portion of flanges 11 adjacent the folds and plate 14 immediately adjacent the upper surface. Normally, printing ap...
