Abstract
A gripping device for thin flexible sheet material comprises a channel member having a longitudinal channel of tapered cross-section opening laterally along its narrow side through one side of the member and containing a gripper bar of generally similar tapered cross-section which is movable laterally toward the open channel side to a gripping position wherein the bar is disposed in wedging relation between and restrained against rotation about its longitudinal axis by the channel side walls. Sheet material to be gripped is inserted through the channel and about the inner side of the gripper bar between the latter and the channel walls in such a way that a tension force on the sheet material draws the bar to its gripping position to effect gripping of the sheet material between the channel side walls and longitudinal gripping surfaces along the sides of the bar. The gripping device described is an anchor bar for a silk screen printing frame or screen chase.
