Method and device in the winding of a web

A method of winding a web onto a succession of cores, comprising:

• (a) locating a first core in a web winding position defined between a first carrier roll and a second carrier roll, said second carrier roll device being closer than the third carrier roll to the first carrier roll,
• (b) attaching a leading end of the web to the core, rotating the core so as to wind the web onto the core and form a reel thereon, resting on the first and second carrier rolls,
• (c) when the reel is completed, reducing the speed of rotation of the core,
• (d) displacing the second carrier roll away from the first carrier roll while the complete reel rest on the first and second carrier rolls and inserting a new core into the space defined between the first and second carrier rolls and the complete reel and returning the second carrier roll towards the first carrier roll, and
• (e) pushing the complete reel away from the first carrier roll towards the third carrier roll, so that the complete reel is supported by the second and third carrier rolls, and lowering the third carrier roll, whereby the complete reel is positioned for transfer to a reel lowering device.

Apparatus for winding a web onto a core, comprising:

• a first carrier roll device,
• a second carrier roll device, which comprises first and second belt rolls of which the first is closer than the second to the first carrier roll device, the first and second carrier roll devices defining a web winding position therebetween for receiving the core,
• a press roll mounted to engage a reel being formed on the core when in the web winding position, whereby the first and second carrier roll devices form respective nips with the reel being wound in the winding position,
• a cutting blade mounted to pivot relative to the press roll for cutting the web when the reel is complete and creating a new leading end for attachment to a new core in the web winding position,
• means for displacing the second carrier roll device away from and towards the first carrier roll device, and
• means for displacing the second belt roll in the vertical direction relative to the first belt roll.
