METHOD AND APPARATUS FOR TAIL THREADING OF A PAPER WEB IN A FINISHING MACHINE FOR PAPER

摘要

In a finishing machine for paper that is arranged to guide a paper web along a predetermined path, a tail of the web or an auxiliary member (6) for transferring the tail of the web is drawn with a traction device (2) comprising power transmission of its own by means of which the traction device moves in relation to a guide (1) extending in the machine direction. The movement of the traction device in relation to the guide is attained by means of a friction contact of one or several drive wheels (3) of the traction device with the guide (1), and the friction contact plane of the guide (1) curves in directions perpendicular thereto in accordance with the travel path of the paper web.
