Provided are an adhesive tape pasting device, mechanism and method for zero-tension double-faced adhesive tape pasting, which belong to foil adhesive tape pasting apparatuses. The adhesive tape pasting device comprises an unwinding station, a winding station, a winding electric motor and an adhesive tape pasting assembly, where after the unwinding station unwinds a double-faced adhesive tape and the adhesive tape pasting assembly pastes an adhesive tape of the double-faced adhesive tape onto a foil, the winding electric motor drives the winding station to wind a remaining release paper of the double-faced adhesive tape. The adhesive tape pasting device further comprises an unwinding driving assembly, where the unwinding driving assembly drives the unwinding station to carry out unwinding work, and in the adhesive tape pasting process, the unwinding work and winding work are carried out synchronously.

An apparatus and a method for dispensing discrete sections of double-sided adhesive tape, comprising a reel support unit whose position is adjustable so as to vary a length of the section of double-sided adhesive tape to be dispensed.
