Claims

[Scope of utility model registration request]

At both ends of a paper path that transports a form folded into a zigzag shape with perforations, a pull-in roller and a discharge roller that sandwich the form and transport it in one direction are disposed, and the form is conveyed in the paper path by the sewing machine. A cutter for cutting from the eye is provided, and elastic pieces are disposed vertically opposite each other so that the upstream side expands at least on both left and right sides of the upstream side of the retraction roller and increases the clamping force on the form as it goes in the approach direction. A burster characterized in that the edge is placed close to the joint of the retraction roller.
