Abstract
A method of conveying and treating a web, wherein the web is first conveyed over a transport surface and then over a rotating transfer roller at the end of the transport surface. The web is transferred from the transfer roller to a treatment roller at a spacing from the transfer roller. The conveying of the web is performed with the proviso and particularly a spacing a between the transfer roller and the treatment roller is set such that the web wraps around the treatment roller over a wrap angle α from 15° to 90°.
Claims13
A method of conveying and treating a web made of fibers, comprising the steps of:
- first conveying the web on a transport surface and then over a rotating transfer roller at a downstream end of the transport surface,
- transferring the web from the transfer roller to a rotating treatment roller at a spacing from the transfer roller in the travel direction of the web,
- setting a speed of the conveying of the web and a spacing of the treatment roller from the transfer roller such that the web wraps around the transfer roller over a wrap angle of 15° to 90°.
An apparatus for conveying and treating a web made of fibers, the apparatus comprising:
- a transport surface for the planar conveying of the web to a rotating transfer roller at the end of the transport surface;
- at least one rotating treatment roller for receiving the web from the transfer roller and in the travel direction of the web downstream n of the transfer roller at a spacing a from the transfer roller, the spacing a between the transfer roller and the treatment roller being such that the conveyed web wraps around the transfer roller over a wrap angle α of over 15°.
A method of operating an apparatus for conveying and treating a web made of fibers, the apparatus comprising:
- a support surface moving and extending in a horizontal travel direction and passing at a downstream end over a transfer roller;
- and
- a rotating treatment roller positioned downstream in the direction at a spacing from the transfer roller, whereby the web is transported downstream on the surface, passes over the transport roller, passes through the spacing to the treatment roller, engages the treatment roller, and is pulled off the transfer roller and conveyed away by the treatment roller, the method comprising the step of
- conveying the web on the support surface and setting the spacing between the transfer roller and the treatment roller such that the web wraps around the transfer roller over a wrap angle of 15° to 90°.
