ROTARY APPARATUS FOR SEVERING WEB MATERIALS |
摘要 |
<p>Disclosed a rotary apparatus for severing a web material, particularly the so called "hard-to-cut materials" such as polymers with relatively high elongation and/or high energy required for failure, including polypropylene (PP), NYLON, polyethylene terephthalate (PET), and any combination thereof, provided in a film form or in a non-woven form. The rotary apparatus can include one or more severing tools such as dies and flex blades. The rotary apparatus provides a speed ratio between the linear velocities of the anvil surface and the severing edge of the severing tool.</p> |
