Abstract
Automatic splicing device for laminar webs in continuous feed processes, consisting of two reel-carriers (1 and 2), mounted above which are the respective preparation heads (3 and 4) and between them a moving head (14) capable of displacement between the positions of said preparation heads (3 and 4), for the preparation in either of these of the web from a reel in stand-by for the subsequent joining to the web of another infeed reel when the latter runs out, without any interruption to the feed process.
Claims4
An automatic splicing device for laminar webs in continuous feed processes, of the type consisting of two reel-carriers, upon which incorporation is made of respective reels (1 and 2), from one of which the infeed web (30) is supplied to the application process, whilst the other is arranged with its web (31) in stand-by to be joined to the infeed web (30) when the corresponding reel runs out, characterised in that mounted above the respective reel-carriers there are respective preparation heads (3 and 4) and between these there is a moving head (14), capable of moving between the positions of said preparation heads (3 and 4), with each of these preparation heads (3 and 4) comprising a fixed roller (6), upon the shaft of which a tilting structure (7) is fitted that is operated by a pneumatic cylinder (8), which structure is fitted at one end with a section (9) for deploying the edge of the web (31) arranged to remain in stand-by, whilst at the other end of said structure (7) there is a roller (10) sheathed in elastic material, upon the shaft of which there is a section (11) that can tilt independently to grip the web (31) against the roller (6).
