<p>PURPOSE:To contrive the improvement of the skew correcting capacity of a form by rotating reversely an auxiliary roller having the outer peripheral surface of a low friction coefficient and moving it backward temporarily, after the tip of the form rushed into a resist roller, and subsequently, rotating forward the auxiliary roller and allowing the tip of the form to rush into the resist roller. CONSTITUTION:The tip of a carried form rushes into resist rollers 1, 2, thereafter, moves backward temporarily to the upstream side of an auxiliary roller 10 by rotating reversely the auxiliary roller 10. The outer peripheral surface of the auxiliary roller 10 is set to a low friction coefficient, therefore, at the time of this moving backward, the skew of the form is corrected. Subsequently, when the auxiliary roller 10 rotates forward, the tip of the form rushes into the resist rollers 1, 2. When it rushes in again, the skew of the form is corrected already. Thereafter, when the resist roller is driven to rotate for a prescribed time by a synchronizing signal, the form is carried to a prescribed part.</p> |
