Abstract

255,298. McLaurin, W. W. Dec. 2, 1925. Testing adhesive strips.-Relates to means for testing, gumming or sealing tape and other adhesive strips of paper, cloth, and other flexible materials. A strip S to be tested is moistened and caused to adhere either to two plates 22, 23 of material similar to that for which the strip is intended to be used, or else to such material carried as a covering by metal plates. By screwclamping means 20, 21 the plates are held between pairs of jaws 10, 18 and 11, 19 respectively, the lower jaws forming the ends of arms mounted on pivots 4, 5 and extended rearwardly as scale-bearing arms 12, 13 carrying sliding weights (not shown). These weights are moved gradually outwards and the points at which clip occurs at the joint formed by the strip is noted. The disruptive force acts in a manner similar to that affecting the strip joining the flaps of a carton.
