Abstract
Laminate unit C obtained by fixing article B to support plate A through pressure sensitive adhesive double coated sheet 1 capable of being deformed by heating to thereby exert a detachment effect is held between a pair of sandwiching means, the sandwiching means so arranged as to enable interposition of the laminate unit C. The laminate unit C is heated by heating means 7 so that the pressure sensitive adhesive double coated sheet 1 is deformed to thereby reduce an area of contact of the pressure sensitive adhesive double coated sheet 1 with the article B with the result that the article B comes up from the pressure sensitive adhesive double coated sheet 1. Thereafter, the article B is detached from the pressure sensitive adhesive double coated sheet 1. Thus, there can be provided method of detaching an article fixed through a pressure sensitive adhesive double coated sheet and a detachment apparatus therefor, which realize effective detachment of articles and ensure suitability to processing by an automatic line.
