IPC: B29C48/92
Filed: 1992-12-25
Abstract: PURPOSE:To provide a synthetic resin sheet having a given width without a defective part at both its margins by reducing the extrusion width to the mimimum by adjusting the inclination of the gap between take-up rolls by a detection signal for the movement of a synthetic resin sheet in the lateral direction and controlling the lateral movement of the sheet by moving it in the opposite direction.

When the sheet is moved laterally in the m direction so that its marginal edge contacts an edge sensor 61, a motor is rotated in the normal direction by the detection signal of the sensor. The bearing on one side of the upper roll is moved downward by the descending movement of a screw shaft so that the sheet is moved laterally in the opposite n direction. On the other hand, when the sheet is moved laterally in the n direction, it is moved adversely in the m direction similarly by the detection signal of the edge sensor 62.
