PURPOSE:To immediately dissolve the elongation of a rubber extruded item and make it possible to perform cutting normally by a method wherein at least two groups of rollers to pinch the extruded item therebetween are provided in tandem in the carrying direction of the item in such a manner that the forward group and backward group of the rollers are rotatingly driven so as to develop the difference between the driving speeds of the two groups of the rollers so as to apply compression to the extruded item in its carrying direction. CONSTITUTION:A weatherstrip W is inserted between rollers 35A and 36A and rollers 35B and 36B. At that time, the rollers 35A(alpha), 35B(alpha), 36A(alpha) and 36B(alpha), which are respectively connected to insertion side driving shafts 31A(alpha) and 31B(alpha), carry the weatherstrip W at a speed which is equal to the carrying speed of a production line. After that, the roller 35A(beta), 35B(beta), 36A(beta) and 36B(beta), which are respectively rotatingly drive by driving shafts 31A(beta) and 31B(beta), carry the weatherstrip W at speed which are slower than those of the respective rollers on the respective insertion sides. As a result, compressive force is applied to the weatherstrip W in the carrying direction and the weatherstrip W which is put in the elongated state is immediately shrunk to its normal dimension and carried to the following process. |
