BURSTER

PURPOSE:To enable a form to be cut off without unnatural distortion by allowing a form runway to be oblique in such a manner that in inclines downward from the feeding roller side to be outlet roller side permitting the form to travel with no slacking. CONSTITUTION:An oblique runway plate which inclines downward from feeding rollers 16 and 17 to outlet rollers 23 and 24 is installed over a form runway 30. A braking roller 35 is fixed in such a way that its center line 35 is located at the position which is 11 distant apart from the contacting point of a pair of the outlet rollers 23 and 24, here 11 is the length of a simple form (the distance between two transversal sewing machine hole lines F1). A form F is pulled into the oblique runway by the feeding rollers 16 and 17 and travels beyond the braking roller 35 with the slacking and is forwarded to the outlet rollers 23 and 24 allowing the form F to be continuously cut off along the sewing machine hole line by means of a primary roller associated with a secondary roller without any distortion while the form is endowed with a tention force by means of a pair of the outlet rollers 23 and 24, the circumferential speed of which is faster.
