Abstract

PURPOSE:To readily and efficiently make a bottomed heat-shrinkable rubber tube to be used for covering a mouth of a bottle or a connecting end of an electric wire, by sealing one of open ends of a heat-shrinkable tube with a curable rubber material. CONSTITUTION:A heat-shrinkable silicone rubber tube having an inner diameter of about 0.8mm. is cut into tubes of 30mm. in length, a rodlike support having an outer diameter approximately equal to said inner diameter is inserted into the cut tube to a depth of 25mm. from one of the open ends thereof, the other open end is sealed with a curable rubber material (for example a silicone rubber containing a curing agent), the sealed tube is heated at 130 deg.C for 5min to obtain a bottomed tube having an open end with an inner diameter of 7.5mm. and a sealed part with an outer diameter of 6mm., and then a length of 4mm. out of the sealed part of 5mm. in length is cut and removed to obtain the intended bottomed heat-shrinkable tube having a bottom thickness of 1mm.. Compared with a method wherein a performed tube with a bottom is stretched to have heat-shrinkability, in the present method the operation is simpler, and the facilities are also plainer.
