ES110230U - Device for welding plastic pipes, perfected (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Device for welding perfected plastic tubes essentially characterized by being constituted by the substantial combination of an electrode with a rotating roller interposing a cloth or similar which electrode is mounted mounted on a support comprising a tension spring being also articulated to the axis of the roller through slots that give reciprocating displacements with respect to that roller, producing in one of said displacements the welding under the influence of oscillating connecting rods that comprise an arcuate end by which they act on bearings incorporated in the support of the electrode. By means of respective cams provided with an attack shoulder substantially adjustable in amplitude because the support of the electrode accompanies the roller in its turn as long as the attack of the shoulder of the cams on the oscillating rods lasts, said support being returned to its initial position according to an inverse rotation with which the action of the tension spring is combined and because the device comprises, at the exit of the roller combined with the electrode, a cutting mechanism composed of a static blade and another soli of a rotating roller acting said mechanism of synchronized cutting with the cams that drive the connecting rods determining the displacements of vaivºn of the - support of the electrode.
