Reivindicaciones

1. Machine for installing sealing caps, in which the sealing caps are stored in an appropriate bin from which they are fed through an adequate slanting channel (3) along which they move by gravity down to the channel's lower end, said sealing caps being designed to be installed on specific containers, particularly over the outlet valve of a container (7) holding gas under pressure, characteristic in that the machine comprises a vertical cylinder (2), the shank of which is located under said lower end of said feed channel (3), said cylinder (2) being vertically aligned with another vertical cylinder (5, 5') forming part of a group of cylinders designed to collect the subsequent sealing caps about to be installed, each of said cylinders (5, 5') being fitted with a respective lower lodging (G, 6') liable to receive and friction-hold the cap being transferred to the installation position. 2. Machine according to claim 1, characteristic in that said group of cap collecting cylinders is preferably formed by two cylinders (5, 5') and is liable to rotate along a horizontal plane when driven by an actuator (4), so that each respective lodging (6, 6') is alternatively positioned facing the cap to be pushed over the cylinder (2) and facing the container (7) outlet valve to which the cap collected from the previous position is to be transferred. 3. Machine according to any of the preceding claims, characteristic in that it comprises a braking element (8) driven by a horizontally positioned cylinder (9) which pushes the container (7) sideways and holds it in the exact position necessary for installing the cap, which is conveniently aligned in a vertical direction.
