PURPOSE:To fix a heat-shrinking tape in a stretched state on a frame, by forming an adhesive surface on one side of a heat-shrinking tape and attaching it to a frame, followed by heat treatment. CONSTITUTION:A heat-shrinking adhesive tape is prepared by forming an adhesive surface on one side of a heat-shrinking tape which has polyethylene film, etc. as base sheet. For example, the tape 13 is attached to a frame 12 in plate form having a large-diameter hole 11 just to cover the hole 11. The frame 12 is turned over and is mounted on a support for heating 14 for heating of the adhesive tape 13 by means of a heater 16 to cause shrinking. Thus tension is generated all over the area of the adhesive tape 13 and the tape is fixed on the frame 12 in a stretched state. |
