CONVERGING GUIDE DEVICE FOR INFLATION FILM

PURPOSE:To provide a converging guide device for an inflation film which enables remote control of the converging angle of the inflation film. CONSTITUTION:A pair of converging guides 4 positioned in the vicinity of the lower side of a receiving roll 2 and facing each other in the shape of generally inverted V are provided. The lower end part of each of these converging guides 4 is joined to a point scale 8 with an operating lever 7 interposed. The operating lever 7 can be moved so that an extension length can be changed by the point scale 8. Within a range of movement of the lower ends of the converging guides 4, a scale plate having scale divisions is provided. A detector 13 reading the scale of a position where the converging guide 4 is located faces this scale plate. The point scale 8 and the detector 13 are connected to a control device 14 and a gap is calculated from the read scale and displayed the gap value on a CRT 15, while the point scale 8 is controlled so that the gap be at a set value inputted.
