Abstract
An assembling device for fabric layers of simple construction providing two plates connected to each other, one of which carries a plurality of needles and the other of which has a series of corresponding holes. The two plates may be brought near to each other, so that the needles jut out from the holes for transfixing the fabric layers, and may be removed so that the plate with the holes slips off the fabric layers from the needles. A locking mechanism is provided with locks, in an unlockable way, the two plates in their approached position.
Claims19
Assembling device for fabric layers, particularly designed for industrial machines, comprising first and second principal elements connected by means in such a way that they may freely move reciprocally between a removal position and an approach position, said first principal element carrying fixed thereto a plurality of needles and said second principal element defining a plurality of holes in correspondence with said needles, in the removal position said needles being gathered in a space included between said two principal elements, in the approach position said needles extending into and through said holes, releasable locking means which lock said first and second principal elements in said approach position, during the passage from said removal position to said approach position said needles jutting out of from said holes for transfixing said fabric layers, while during the passage from said approach position to said removal position said second principal element provided with the holes slipping off the fabric layers from said needles.
