Abstract
A quantum of liquid adhesive is encapsulated in an ampule-like frangible capsule. An instrumentality is provided by which the adhesive-containing capsule may be temporarily secured on one surface of two objects which are to be adhered together in a surface-to-surface manner. For instance, a foraminous paper band is looped around the capsule and thumbtacked to one of the objects. Several similar adhesive-containing capsules may be similarly temporarily secured on one or the other of the objects, these capsules being distributed in a pattern calculated to cause sufficient adhesion of the two surfaces upon application of the adhesive thereto. Then the two objects are placed in surface-to-surface, confronting relationship and one of the objects is pressed toward the other, for instance by tapping its accessible side with a hammer everywhere that there is an adhesive-containing capsule disposed on the now inaccessible side. Thus, each capsule is broken and its adhesive spread in a patch between the two surfaces, adhering the two objects together.
