A glue raising roll 413 for transferring glue in the basket 44 to a glue roll 48; a glue roll 48 for applying glue on the back of the cloth; a doctor roll 47 for adjusting the amount of glue in contact with the glue roll 48; A leveling roll 49 that applies an appropriate tension to the cloth C and feeds it forward is arranged in parallel with the side plate of the glue basket 44 so as to be interlocked with each other via a gear and in parallel with a predetermined interval. Is supported by a simple bearing plate.

  On the other hand, in the upper structure 43, the upper pinch roll 410 that forms a pinch roll paired with the feed roll 46, and the roll and gear arranged in the lower structure 42 are linked to each other and glued to the cross C. A drive roll 412 for applying a feed tension toward the front of the machine body and a press stay 411 for pressing the cross C from above between the upper pinch roll 410 and the drive roll 412 are parallel to each other at a predetermined interval. As arranged, each is pivotally supported by the bearing frames on both sides of the main body of the upper structure 43.

  Further, a pair of legs 431 that support both side edges of the lower structure 42 are crossed from a raw roll 440 that passes through a central axis of a cross core rod 441 supported at the tip of a cross receiving bracket 442. A first tension bar 432 which is in contact with C and applies a pulling load at the pulling port of the pasting machine body is bridged. Above that, a second tension bar 433 is also bridged, which is also in contact with the cloth C and applies a pulling load at the pulling port.
