摘要

A device (16) for seating seals (6) automatically in the grooves (14) afforded by the sockets (3) of plastic pipes (4) comprises a straight tubular element (1) offered immediately adjacent to and in alignment with the pipe socket (3) and serving to support and position a seal (6) of outer diameter greater than the internal diameter of the socket, a plunger (7) capable of sliding movement internally both of the tubular element and of the socket, by which a seal positioned in the tubular element is inserted into the groove (14), and actuators (10) by which the plunger is reciprocated automatically.
