IPC: E04C5/07
Filed: 2009-06-03
Abstract: A composite reinforcing bar is formed from a series of inner rovings with first and second helical wrappings of at least one roving wrapped around the inner rovings in opposed directions of wrapping with the resin permeated therethrough. The bar structure is formed to allow torsional bending sufficient to allow the formed bar to be wound to form a coil of the bar wrapped a series of times around an axis at right angles to the length of the bar. The bar is forwarded into a rotating winding frame formed by a series of posts around a vertical rotation axis. The coil is held in place while the frame is removed for transporting the coil to a remote location. At the remote location the coil is placed in a similar winding frame and the bar is pulled from the coil and cut to a required length.

Abstract: A canvas or material stretching system designed to allow an inexperienced user to stretch a canvas or material on a frame without the use of stretching pliers and staples, both of which require considerable skill and strength. Special purpose corner clamps are used to secure the stretcher bars into an initial open miter frame.  The purpose of this is to orient the double sided adhesive strip on the side of the stretchers towards the canvas or material while maintaining the adhesive strip from touching the canvas or material. Once alignment is achieved, the stretching bars are pressed down and attached onto the canvas or material and the corners are released. The corner clamps are removed and canvas or material corners are cut and folded into the open miter ends which also have adhesive strips. By rotating the stretchers axially 90 degrees into the final frame, thus closing the miters, and upon inserting U-shaped fasteners into grooves placed on the back of the stretcher the canvas or material is stretched and ready to display.
