摘要

#CMT# #/CMT# A strip of a suitable plastic film(10) is printed(11). Parts forming the windows(14) are then punched out. #CMT# : #/CMT# Printed parts may be punched and embossed on the same equipment. Adhesive(12) is applied to the under side of the plastic film(10) and a carrier strip(13) applied over the adhesive. A protective film can be applied to the plastic film before the punching and embossing stage. #CMT#USE : #/CMT# For manufacturing windows for communications equipment, e.g. mobile telephones. #CMT#ADVANTAGE : #/CMT# The process is simpler and less costly compared to existing injection molding and printing processes. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic front and side views of the construction of a display window. 10 : plastic film 11 : printed area 12 : adhesive 13 : carrier strip 14 : window.
