Apparatus and method for splicing the trailing edge to the leading edge of two material webs and/or apparatus for unwinding a material web from of a supply roll

摘要

it is a device to connect to the endstu00fcckes first materialbahn (2) with the anfangsstu00fcck a second materialbahn (3) described the first abrollriemen (4) on the roll of the first materialbahn (2), by means of a first abrollriemenantriebswalze (5) antreibbar, e a second abrollriemen (6) on the roll of the second materialbahn (3)using a second abrollriemenantriebswalze (7) antreibbar and spleiu00dfeinrichtung (8) with two pru00e4gewalzen (9,10) for verpru00e4gen of endstu00fcckes with the anfangsstu00fcck in at least one of the pru00e4gewalzen with (9, 10) by means of a spleiu00dfantriebswalze (11) antreibbar. the device is cost-effective, space saving and easy to be trained.the solution of this problem is proposed, and the first and second abrollriemenantriebswalze (5.7), and the spleiu00dfantriebswalze (11) by means of a single motor (13) to make antreibbar and between the first abrollriemenantriebswalze (5) and the first abrollriemen (4)the second abrollriemenantriebswalze (7) and the second abrollriemen (6) and the spleiu00dfantriebswalze (11) and at least one driven stamping roller (9) each have a coupling arranged through the respective antriebsverbindung either manufacturing or is solvable.
