LIQUID PRESSURE TRANSFER PRINTING METHOD OF STEERING WHEEL RIM FOR AUTOMOBILE AND MASKING TAPE CUTTING APPARATUS USED THEREFOR

摘要

A steering wheel rim (22) for an automobile by using a liquid pressure transfer printing methods is manufactured by attaching a masking tape (18) to a boudary portion of the steering wheel rim to be separately transfer-printed, marking a conjunction line (8a) by using a blade (25) in the middle portion the masking tape and detaching a lower half portion of the masking tape, covering an upper portion of the masking tape, performing transfer printing a surface lower than the conjunction line and cleaning and drying the transfer-printed surface and removing the masking tape and a protective masking tape (18c), secondly attaching another masking tape to a first transfer printing boundary portion of the steering wheel rim, marking a separation line (8b) by using a blade at a position about 0.05-0.2 mm lower than the conjunction line and removing the upper half of the protective masking tape, covering the lower portion of the masking tape and the lower portion of the masking tape with a protective masking tape, and after secondly performing transfer printing on an upper surface of the conjunction line and cleaning and drying the transfer-printed surface, removing the masking tape and the protective masking tape. Also, a cutting apparatus for performing the above steps includes a horizontal rotary pedestal (20) on which the steering wheel rim is placed, a clamp (23) for fixing the steering wheel lamp, and a blade holder (24) for marking a cut line at a uniform height.
