PURPOSE:To make the use of a double station type molder possible and, at the same time, contrive to prevent the accuracy of the pasting position of a label from lowering in high speed continuous molding by a method wherein a label inserter is arranged above split molds so as to engage the label to a cavity by its vertical sliding. CONSTITUTION:Under the condition that split molds 4a and 4b are opened, a cylinder 13 is actuated so as to project a sucking means 14 in order to suck a label 3 in a label magazine 16 and, after that, actuated so as to retreat the sucking means 14. Next, by actuating a cylinder 11, the cylinder 13 is shifted to the position corresponding to the cavities 6 and 6 of the split molds 4a and 4b so as to abut the label 3 against the cavities 6 and 6. Under the state just mentioned above, the suction of the sucking means 14 is stopped and, on the contrary, the vacuum suction is actuated through the vacuum vents 6a and 6a of the cavities 6 and 6, resulting in transferring the label 3 to the cavity side. After that, the cylinder 13 is moved upwards to the position of the label magazine 16. Next, after a parison 8 is pinched off by closing the split molds 4a and 4b, a blowing nozzle 9 is struck in the parison so as to blow pressure fluid in the parison 8 in order to expand the parison, resulting in abutting the parison against the cavities 6 and 6 and, at the same time, welding the held label 3 to the parison 8 in order to produce a hollow container. |
