A roll B is formed by winding the material A on the paper tube a while suppressing the rebound of the paper tube a by a press roller 25 pivotally supported in a frame f pivotally supported on the upper part of the roll. It is something that goes. Roll B is put on a slitter to make a sewing tape or the like.

The pair of rollers 21 and 22 is a rubber roller in which the front side is a plated roller and the rear side is covered with rubber, and right and left opposite spiral spiral protrusions from the center to the left and right in the vicinity of their lower sides. Two expansion rollers 41 and 42 are provided horizontally and parallel to each other in which the strips 40a and 40b are formed and are rotated in a direction in which the material A that abuts immediately before being wound up is expanded to the left and right.

More specifically, the rollers 21 and 2 will be described.
2 are spaced apart from each other so that the paper tube a does not drop, sprocket wheels 21a and 22a are fixed to their end shafts, and the chain 23 is reversibly variable speed motor M1.
It is adapted to be rotated in the above direction via. The press roller 25, which is supported on these rollers 21 and 22 and holds the roll B whose diameter is increased by winding the material A around the paper tube a so that it does not jump up, is installed upright on the rear part of the machine base F. It is pivotably supported in front of a frame f pivotally supported by left and right columns 26, 26.
A pair of left and right low-friction cylinders 27, 27 are provided between the rear end of the frame f and the rear part of the machine base F, and a predetermined air pressure is supplied via a precision pressure reducing valve 28. That is, even if the diameter of the roll B becomes large and the cylinders 27, 27 are compressed, the pressure is released by the pressure reducing valve 28 and a predetermined selected pressure is continuously supplied to the cylinder 27. The cylinders 27, 27 also serve to lift the press roller 25 upward when the roll B is taken out after the winding operation is completed (operated by SWI). When it is desired to wind it harder, the supply air pressure to the cylinder 27 is set higher.

The guide means 30 for contacting both end surfaces of the paper tube a to prevent left and right shakes is a pair of left and right expandable rods urged so as to contact both end surfaces of the paper tube a and the upper ends thereof contact the press rollers 25. 31 and 31, and a pair of left and right moving bases 32a and 32b that accommodate springs that accommodate these rods and urge them upward
