Splicing apparatus for splicing material webs for the production of power storage devices, machine comprising the splicing apparatus and relative splicing method

A splicing apparatus for splicing two material webs for the production of power storage devices provided with a splicing assembly comprising:

• at least two feeding units, each configured to feed a respective material web;
• and
• a splicing unit configured to receive the two material webs and to splice the two webs by means of an adhesive tape applied on one of the two webs;
• the splicing unit comprising a movable deflecting element, which is arranged close to the first material web and is configured to move along a splicing surface defined by the two material webs to be spliced, so as to stretch the first material web during the splicing of the two webs;
• the deflecting element being movable between a disengagement position, in which the deflecting element is spaced apart from the first material web, and a transfer position, in which the deflecting element at least partially engages the first material web so as to at least partially stretch it when the web is released onto the second feeding unit.
