To provide a drawing machine having a simple structure capable of operating at a high speed, which draws a sheet material using an endless link device composed of a plurality of isometric link devices formed in a folding-scale shape.

An endless link device equipped with holding tools for holding plurality of the edges of a thermoplastic resin sheet material at both the ends of the sheet material is provided, and the endless link device comprises plurality of isometric link devices formed in an isometric folding-scale shape. The endless link device is driven by a chain wheel at the inlet side of the sheet material and guided by a guide rail structured diversingly in forwarding direction to draw the sheet material, and then the sheet material is released and the endless link device is driven by a chain wheel at the outlet site to return to the chain wheel at the inlet side. In the device, a pair of radial bearings are provided in a peripheral part of the bearing equipped on the lowest end of a link axis for a joint of a link plate forming the folding scale part in the link device in such a way that the radial bearings roll on the both surface sites of a guide rail for controlling a movement of the link device.
