The manual handle 12 is rotatably and non-removably supported on the base end of the tubular shaft 6 by means of an iron connection between a screw 13 and a concave side 14, and the base end of the tubular shaft 6 is supported on a frame (not shown).
The tubular shaft 6 is freely rotatably supported through a bearing 15 and constructed in a state where one side is stopped.
A cone 16 is slidably fitted between the end of the cylindrical winding core A' of the cut material A and the tubular shaft 6 on the outside of the cylindrical shaft 6, Three four-stage pulleys 17, 17', 18 are arranged in an inverted triangular arrangement on a plane perpendicular to the axial direction of the tubular shaft 6 on the side, and the upper two pulleys 17, 17' An electric motor 21 is attached to rotating shafts 29, 29' parallel to the tubular shaft 6 so that its intermediate point is located directly below the tubular shaft 6, and the lower pulley 18 is fixed to the upper side of a base plate 20 that can swing up and down. and is attached to a rotating shaft 23 driven by a reducer 22, and four belts 19 are connected to the upper two pulleys 17, 17'.
At the same time, one end of the gourd to be held is placed on the belt part 19' of the belt 19 by slightly manipulating it, so as to apply a rotational force to the gourd, and A rotary round blade 24 is disposed above the tip of the tubular shaft 6, and this rotary round blade 24 is attached to the middle of a lever 25 via bearings 26, 216', and the lever 25 is mounted on a frame (not shown) up and down. When the lever 25 is swung downward, the round blade 24 comes into pressure contact with the workpiece A to be cut, and rotates freely by the rotational force of the workpiece A. An idler wheel 27 is arranged above the wheel-cut object A to press the wheel-cut object A from above and prevent it from dislocating, and this idler wheel 27 is mounted on a support (not shown) that is erected on a mount. ) via bearings 28, 28' so that it can move up and down.

That is, in the description above, a synthetic resin film wrapped around a cylindrical core.
To cut the material to be cut into pieces, such as a sheet material, first twist the manual handle 13 to move the rod 8 and cone 10 to the position shown by the imaginary line in FIG. Stop piece 4
. . . After the group is in a constricted state, the cylindrical winding core A' of the ring-cut material is assembled on the tubular shaft 6, and then the manual handle 12 is twisted in the opposite direction to the above to tighten the rod 8 and the conical body 10. is moved to the position shown by the solid line in FIG. A cone 16 is joined between the end of the cylindrical winding core A' and the tubular shaft 6, and the front end of the cut material A is mounted on the control part 19' of the belt 19.
Place the cutting part of the wheel-cut object A under the rotary round blade 24 to fix the wheel-cut object A, and at the same time push down the idler wheel 27 to cut the wheel-cut object A from above. Then the electric motor 22
The rotating shaft 23, pulleys 17, 17', 18
Then, while rotating the belt 19... to rotate the cutter, press the lever 25 to press the rotary round blade 24 against the cutter to be cut, and move the base plate 20 downward. The electric motor 21, reducer 22, and lower door are swung. -
By pressing down the pulley 18, the lower part 1 of the belt 19 is removed.
9' is sequentially tightened to raise the object to be discussed (A), in other words, push down the rotary round blade 24 while pushing up the object to be cut (A). It is used for purposes such as rolling over a round cut piece A, cutting the round cut piece A toward its center, and cutting it to the cylindrical winding core A' to complete round cutting. Since the present invention is constructed as described above, by using the method as shown in the above embodiment, it is possible to cut a synthetic resin film/sheet material wound around a cylindrical core into ring shapes. In particular, in the present invention, a cone that fits between the end of the cylindrical winding core of the cut material and the tubular shaft is slidably fitted on the outside of the rear part of the tubular shaft. Therefore, if there is a gap between the inner surface of the cylindrical core and the outer surface of the tubular shaft, this cone can be pushed into the rear end of the cylindrical core and the opening of the tubular shaft. This cone and the locking piece of the holding member hold the cutting member parallel to the axial direction of the tubular shaft, allowing accurate round cutting perpendicular to the longitudinal direction of the tubular shaft. It has the advantage of being able to

In addition, the tubular winding core of the workpiece to be cut is iron-locked to a horizontal punch whose diameter is freely tensionable and rotatably supported at both ends in a receiving part, and by rotating this horizontal punch, the workpiece is cut into a ring. A patented method for cutting a ring-cut object wound around a tubular winding core, which is rotated and a cutting knife is brought into contact with the rotating object to cut the ring-cut object into circular slices. It is known from the No. 234 Ship Bulletin, etc., but in this type, when the tubular core of the ring-cut material is iron-bonded to the Yokomura, or when the cut material is taken out from the Fujimura, one end of the Fujimura is used. This has had the disadvantage of requiring a cumbersome and inefficient operation of removing the bolt from the collar receiving part, performing the conflict and taking it out from the removed part, and then re-locking the same part to the ratchet receiving part.

The present invention solves such defects, namely, three pulleys are placed on the lower side of the tubular shaft on a plane perpendicular to the axial direction of the tubular shaft, and the middle point of the upper two pulleys is arranged in a tubular shape. The belt is placed in an inverted triangular arrangement so as to be located directly below the shaft, and these pulleys are used to slightly manipulate the belt between the two upper pulleys and run it around in an inverted triangular shape. An electric motor and a speed reducer, in which one end of the cut object is mounted on a rack to apply rotational force to the cut object, and the lower pulley is fixed to the upper side of a base plate that can swing up and down. Since it is fixed to a rotating shaft driven by a rotary wire, it is possible to connect the tubular winding core of the cut material to the tubular shaft and take out the cut material from the tip of the tubular shaft, which is always open. As described above, the present invention has the advantage that the work can be done much more easily and efficiently than the above-mentioned known method.
