<p>PURPOSE:To achieve the complete bonding and integration of a carpet with rubber without causing the deformation and the hardening of the pile of the carpet, by applying an unvulcanized rubber sheet to the back surface of the carpet inserting a cushioning material therebetween with a press without heating, and vulcanizing the rubber under atmospheric pressure. CONSTITUTION:The carpet 1 is contacted and laminated with the unvulcanized rubber sheet 3, and the obtained laminate A is inserted between a pair of vertically arranged press molds 5, 5'. The cushioning materials 4, 4' composed of felt, sponge rubber, etc. are inserted between the laminate A and the press molds 5, 5', and the laminate A is hot-pressed. The heating temperature is adjusted to a level (about 60 deg.C) to keep the pressed carpet files 1' from permanent deformation and hardening. The bonded laminate A is taken out of the molds, and the rubber sheet is vulcanized under atmospheric pressure to bond the rubber sheet firmly to the back surface of the carpet. The heating operation can be omited by preheating the unvulcanized rubber sheet 3.</p> |
