Description of the Related Art Generally, when a sheet-like material such as a synthetic resin film, paper, or aluminum foil is cut in the width direction during traveling, for example, as disclosed in Japanese Patent Publication No. 63-20678. A cutter whose blade edge is gradually inclined away from the sheet-like object surface in the forward direction, a spatula that moves together with the cutter and supports the sheet-like object surface from the side opposite to the cutter, and the cutter and spatula. A cutting device constituted by a driving means for moving the sheet-shaped article over the entire width is used.

点である。A thin sheet-like material having a small thickness and a small rigidity is cut by a cutting device composed of one cutter and one spatula for supporting the sheet-like material as described above. In this case, even if the sheet-shaped material is supported by the spatula and introduced into the cutting position of the cutter, the sheet-shaped material is only pressed to the spatula side and is not cut by the cutter, and it accumulates at the intersection of the cutter and the spatula. This is the point that the sheet-like material is broken and the cutter is damaged.

It is necessary to press the sheet-like material 30 suspended between the empty core 20 and the auxiliary roller 4 tightened on the winding shaft 3 located at the position downward by the spatula of the cutting device so as to be tensioned and cut. When the sheet material 30 is cut in such a state, the cutting position becomes a position away from the empty core 20 tightened by the winding shaft 3, and the end of the cut sheet material 30 hangs down, resulting in empty core. It is difficult to wrap around 20.

Reference numeral 2 is a levo helving arm rotatably attached to a machine base (not shown) by a bearing, and the winding shaft 3 can be attached and detached. Take-shaft 3 is fastened a single or multiple several cores 20, it is formed so as to be rotatable by a bearing.
Reference numeral 4 is an auxiliary roller for switching the sheet-like material from a full core to an empty core. Reference numeral 5 denotes a cutting device which is installed in parallel with a surface pressure imparting roller 1 at a winding operation position of the sheet-like material 30 and a lower position close to the winding shaft 3. A rail member 6 is attached to a machine base (not shown) in a horizontal state in a direction orthogonal to the traveling direction of the sheet-like material 20. Reference numeral 7 is an electric motor attached to the end of the rail member 6, and a drive pulley 8 is attached to the output shaft. A driven pulley (not shown) is rotatably attached to the other end of the rail member 6, and a belt 9 is stretched between the driven pulley 8 and the driven pulley. A traveling member 10 is movably attached to the rail member 6, and is integrally attached to the belt 9. The electric motor 7, pulley 8, belt 9
A fluid cylinder may be used instead of the above. 1
1 is a bracket attached by bolts 12 to the traveling member 10, thus mounted to the bolt 15 in a state of gradually inclined in a direction away from the lower surface of the sheet 30 the supporting member 13 at the top toward the traveling direction ing. The support member 13, the columnar body of trapezoidal cross-section of the split or
Using the columnar body bored cutlery mounting groove in a part of the trapezoidal cross-section. Reference numeral 14 denotes a blade attached vertically to the support member 13, and the blade edge 14a of the blade 14 and the support member 1
The crossing angle (θ) of the supporting portion 13a of the sheet-shaped article 3 is an obtuse angle, preferably 150 ° or more and 180 ° or less. The crossing point between the cutting edge 14a of the cutting tool 14 and the supporting portion 13a of the sheet-like material of the supporting member 13 is the cutting position.

シート状物３０の切断部に所定の張力が作用せず従来の
切断装置の場合とほとんど変わらなかった。If the length (L) of the horizontal portion of the support portion 13a is extremely small, the end portion becomes sharp, and the sheet-like material is subjected to an unnecessarily large tension, so that the sheet-like material 30 has a sharp edge. May be torn by the support 13a , and when the length (L) of the horizontal portion is set to 5 mm or more, a predetermined tension does not act on the cut portion of the sheet-like material 30, which is almost the same as the case of the conventional cutting device. There wasn't.

巻取られる。When a preset amount of the sheet-like material 30 is wound up by the above-mentioned winding machine, the revolving arm 2
Is rotated to move the fully wound core to the doffing operation position and the empty core to the winding operation position. Then, the electric motor 7 of the cutting device 5
(Not shown) is operated and the belt 9 causes the traveling member 10 to move.
When the support member 13 and the blade 14 travel in the width direction of the sheet-like object 30, the sheet-like object 30 is supported by the supporting portion 13a.
Then, the cutting portion of the sheet-like material 30 is just lifted, and the blade 14 is cut while being lifted on the blade 14 in a state where a tension larger than the winding tension acts on the cutting portion. Since the blade 14 is attached to the support member 13 so that the crossing angle (θ) between the blade edge 14a of the blade 14 and the support portion 13a of the sheet-shaped object 30 of the support member 13 is an obtuse angle,
The sheet-like material 30 does not accumulate at the cutting position, which is the intersection of 4a and the support portion 13a, and it is possible to reliably cut without wrinkling. Then, the cut sheet-like material 30 is wound around the peripheral surface of the empty core 20 by the accompanying airflow accompanying the rotation of the empty core 20, and an adhesive is applied to the peripheral surface of the empty core 20. When a double-sided adhesive tape or the like is attached, the sheet-like material 30 is adhered to the empty core 20 and wound up. On the other hand, the cut sheet-like material 30 on the side of the fully wound core is wound on a sheet roll.
