ABSTRACT:
A device for attaching an object to a substrate by means of glue includes at least one part (21) provided with a breakable sealed cavity, each containing one of the glue components, and one or more cavities (22) in the device (20), which are filled with the remaining glue components, where the parts (20, 21) are movable relative to each other like a piston pump, which makes the glue components flow towards a gluing surface (24, 42) through a system of channels (29, 30) and optionally through mixing chambers (31) and where the breakable seal (26) is broken by this movement. In order not to obstruct an equal flow of glue components, the device according to the invention comprises a cam (27) and a seal storing chamber (35) to store the seal away from the flow after it is broken.
