SPREADING ELEMENT, SPREADING-ELEMENT RING, DEVICE FOR SPREADING A FLAT MATERIAL WEB, SPREADING ROLLER FOR LATERALLY SPREADING OUT A FLAT MATERIAL WEB, METHOD FOR SPREADING A FLAT MATERIAL WEB AND APPARATUS FOR HANDLING FLAT MATERIAL WEBS

摘要

In order to improve, in particular, a spreading roller (1) for laterally spreading a flat material web (2) which is moving in a transporting direction, the invention proposes a spreading element, or a spreading-element ring (15), having a contact-leg part (25) which forms a contact surface (26) and is intended for interacting with the flat material web (2), having a foot part (27) for arranging on a rotational body (7), and having a connecting part (28) which connects the contact-leg part (25) and the foot part (27), wherein at least one region of the connecting part (28) between the contact-leg part (25) and the foot part (27) is less stiff than a neighbouring region.
