Abstract

PURPOSE:To automatically stick a pressure sensitive adhesive tape to a sticking object, and increase efficiency in dispatch of business by feeding the pressure sensitive adhesive tape by cooperation between a feed roller arranged in the rear in the delivering-feeding direction of the pressure sensitive adhesive tape with a cutting part as a boundary and a delivery roller arranged in the front in the delivering-feeding direction of the cutting part. CONSTITUTION:A pressure sensitive adhesive tape T is fed by cooperation between a feed roller 24 arranged in the rear in the delivering-feeding direction of the pressure sensitive adhesive tape T with a cutting part 46 as a boundary and a delivery roller 32 arranged in the front in the delivering-feeding direction of the cutting part 46. Thereby, since the cutting part 46 is placed, the pressure sensitive adhesive tape T can be sent while sandwiching the front and the rear, and can reliably and smoothly be fed. At the same time, even if the respective cutting ends are put in a separate condition at cutting time, the tape can reliably be fed. Thereby, it can be used for a plate-like body such as a calendar or a poster without limiting to an envelope, and can be used even for a double- sided tape or the like without limiting to a single-sided tape.
