<p>PURPOSE:To reliably wind the leading edge of a sheet round a take-up shaft by sucking the air between a take-up reel and a flange into a take-up shaft with the rotation of the take-up reel. CONSTITUTION:When the leading edge of a film advances along a guide plate 12 and makes a round of a take-up shaft 11a, the air in a portion surrounded by a circular-arc portion of the film F and the outer periphery of the take-up shaft is caused to flow in the arrow direction and sucked in the shaft 11a to be circular-arc in the periphery of the shaft 11a. There is a difference in air pressure between the outside and inside of the film F, so that the film F is strongly adsorbed to the shaft 11a to cause the leading edge of the film wind round the shaft 11a, and subsequently, the film is taken up on the take-up reel with the rotation of the take-up reel. The air sucked in the take-up shaft 11a is discharged from the side of a flange 11b to the outside.</p> |
