Method for manufacturing rotating bands, involves providing plastic material that is supplied to blowing nozzle in plasticized form, where plasticized plastic material is blown out from discharge nozzle to film-like continuous plastic tube
摘要
<p>The method involves providing the plastic material that is supplied to a blowing nozzle (16) in plasticized form. The plasticized plastic material is blown out from the blowing nozzle to a film-like continuous plastic tube (17). The individual tube sections are separated from the continuous plastic tube along the separation lines running transverse to direction of the production line (22). An independent claim is also included for a device for manufacturing rotating bands.</p>
