Title: Apparatus for adhesion treatment
Inventor: INOUE KIYOSHI
IPC: C09J5/00
Filed: 1979-03-13
Abstract: PURPOSE: To make a strong adhesive bond by spreading an interposed adhesive into a layer thin enough to enhance the cohesive force, by giving relative movement under pressure to adherends while keeping them in the state in which the adhesive is interposed between them.  
     CONSTITUTION: The adhesion treatment consists of abutting adherends 7 and 8, each fixed on a chuck, and rubbing the adherends with each other by pressing and rotation. The rotation is effected by a motor 3 when a clutch is coupled by operation of a control lever 4c, and the pressing is effected by a cylinder 5. By the action of the pressing and rotation, an adhesive 9 interposed between the adherends is pressed down to the surfaces of the adherends, thereby enabling the adhesive to closely adhere to the surfaces and penetrate well into the concavities of the surfaces. Further, by the action, included bubbles and impurities are pushed aside and the adhesive adheres uniformly to the surfaces. An excess adhesive is squeezed out so that an adhesive layer which is thin to such an extent that uncoated spots are not present is formed.
