BALANCED STENCIL FOIL TENSIONING FRAME WITH FOIL ALIGNMENT FIXTURE

摘要

A balanced stencil foil tensioning frame with a foil alignment fixture removes the need for the complex air/bladder arrangement of conventional systems by pivoting side members to engage foil. With less components, the tensioning frame system is reliable and light weight with few moving parts. In one embodiment, a base member can receive a stencil foil and a frame top can lock into the base member, depressing the edges of the stencil foil. The amount of provided depression can adjust the tension of the foil. In another embodiment, a plurality of tension segments can move in a linear direction to create a uniform foil tension. The alignment fixture can be wall mounted to hold foil in a vertical position. This allows for consistent alignment and attachment of foil to the tensioning frame.

主权项

1. A balanced stencil foil tensioning frame comprising:
tensioning frame members forming a foil frame, wherein at least two of the tensioning frame members are pivoting members rotating about an axis generally parallel with at least two edges of a foil disposed in the foil frame, the pivoting members pivoting between a foil untensioned state and a foil tensioned state; linear tension segments disposed along a foil facing side of the foil frame, the linear tension segments having a protrusion extending therefrom that engages with a recess disposed about an outer perimeter of the foil, wherein the pivoting members are rotated to the foil tensioned state to cause the protrusion to apply tension to the foil.
