Abstract
A winding roll presser device that presses a winding roll by the entire width thereof, the winding roll being formed by a reel spool and a long material wound therearound, said device includes a plurality of rotational rolls arranged in parallel with one another in the width direction, a belt tensely wound so as to cover the plurality of rotational rolls, a first drive unit for moving the belt from a stand-by position so as to bring the belt into contact with the winding roll, and a second drive unit for pressing the winding roll with a straight part of the belt.
Claims11
A winding roll presser device that presses a winding roll by the entire width thereof, the winding roll being formed by a reel spool and a long material wound therearound,
- said device comprising:
- a plurality of rotational rolls arranged in parallel with one another in the width direction;
- a belt tensely wound so as to cover the plurality of rotational rolls;
- a first drive unit for moving the belt from a stand-by position so as to bring the belt into contact with the winding roll;
- and
- a second drive unit having different rotational axes from the first drive unit for pressing the winding roll with a straight part of the belt.
A method of winding a long material around a winding roll via a nip, in which the long material is transported on a reel drum and the nip is formed by the winding roll contacting the reel drum, said method comprising the steps of:
- a) rotating a winding roll presser device that presses the winding roll by the entire width thereof, at a speed equivalent to the rotational speed of the outer periphery of the winding roll;
- b) bringing the winding roll presser device from a stand-by position into contact with an outer periphery of the winding roll by a predetermined length in the transporting direction of the long material, while still winding the long material around the winding roll;
- c) increasing a linear pressure on the winding roll presser device to a predetermined level for a predetermined period during the winding of the long material;
- d) cutting the long material before the reel drum;
- e) separating the winding roll from the reel drum after a linear pressure on the nip is reduced to zero;
- and
- f) stopping the rotation of the winding roll and the winding roll presser device.
A method of winding a long material around a winding roll via a nip, in which the long material is transported on a reel drum and the nip is formed by the winding roll contacting the reel drum, said method comprising the steps of:
- a) rotating a winding roll presser device that presses the winding roll by the entire width thereof, at a speed equivalent to a rotational speed of an outer periphery of the winding roll;
- b) bringing a first portion of the winding roll presser device from a stand-by position into first contact with the outer periphery of the winding roll by means of a first driving unit of the winding roll presser device, and bringing a second portion of the winding roll presser device into second contact with the outer periphery of the winding roll by means of a second driving unit so as to allow the winding roll presser device to be in contact with the winding roll over a predetermined length in the transporting direction of the long material;
- c) increasing a linear pressure of the winding roll presser device against the winding roll to a predetermined level;
- d) cutting the long material before the reel drum;
- e) separating the winding roll from the reel drum after a linear pressure on the nip is reduced;
- and
- f) stopping the rotation of the winding roll and the winding roll presser device.
