ABSTRACT:
A splicing device for label webs mechanically holds the leading end of the new web and is rapidly transferred to splicing position and accelerated into the running speed of the web while the rotational speed of the web supply spool that is associated with the leading end of the replacement web is initially gradually adjusted to the running speed of the label web. The leading end of the replacement web and the trailing end of the expiring web are glued in an overlapping manner. The splicing device has two identically constructed multi-functional drums which are arranged to function alternately and are equipped with a gripper, cutter, free running deflector roller and pressure application device.
