Document Type and Number:
Japanese Patent JPH09500859
Kind Code:
A
Abstract:
The invention concerns a method in winding of a web, wherein the web (W) is wound onto a spool (14) a support of a support roll (16) while passed through a nip (N) formed between the support roll (16) and the roll (15) that is being produced. The spool (14) is supported at least partly. The spool (14) / the roll (15) is supported and/or loaded by means of a device (20) whose position can be shifted. At the initial stages of the winding, the loading/supporting unit/units (24) of said device (20) is/are shifted substantially in the plane passing through the axes of the support roll (16) and of the roll (15) that is being produced so as to load and/or to support the roll (15) that is being produced in the winding position. When the winding makes progress, the loading/supporting unit/units (24) of the device (20) is/are shifted downwards substantially along a path parallel to the circumference of the roll (15), and, at the final stages of the winding, the roll (15) that is being produced is supported by means of said unit (24) from underneath. The invention also concerns a device in winding of a web for carrying out the method. The device (20) is fitted to be used when a web (W) is wound onto a spool (14) on support of a roll (16) while passed through a nip (N) formed between the roll (16) and the roll (15) that is being produced, which spool (14) is supported at least partly by a support member placed in the centre of the spool (14). The device (20) comprises a unit (24) for supporting the spool (14) and for loading the roll (15). The unit (24) is fitted as a combined loading/supporting and surface-drive member. The device (20) comprises means for shifting the unit (24) substantially in the plane passing through the axes of the support roll (16) and the roll (15) that is being produced and substantially along a curved path parallel to the circumference of the roll (15).
