Abstract

A machine for applying safety strips to the upper part of containers. The machine has, along a container advancement path, at least one application station which includes at least one application assembly provided with at least one crimping device which includes a first pad, designed to make contact, with a working face thereof, with a first end of the safety strip applied to the corresponding container at a transfer station, and a second pad, which is provided, on its working face, with at least one suction port, for the removable retention of a second end of the safety strip; each application assembly includes a respective suction device which is connected to the suction port of the corresponding second pad.

Claims9

Dependent claims

A machine for applying safety strips to an upper part of containers, comprising:

conveyance means for conveying the containers along an advancement path, said conveyance means having retention heads designed to act upward on the containers, along said advancement path there being in mutual succession at least one transfer station, configured to transfer to the upper part of the containers a respective safety strip arranged substantially vertically and with a first end thereof, located in a lower region, applied to a first lateral portion of a corresponding container and a second end thereof, located in an upper region, applied to a retention head that acts on the corresponding container, and at least one application station which comprises at least one application assembly which is configured to move substantially parallel to at least one portion of said advancement path of the containers and in a manner which is synchronized with the movement of the containers on said conveyance means, in order to follow a respective container, said at least one application assembly having at least one crimping device which comprises a first pad, designed to make contact, with a working face thereof, with the first end of the safety strip applied to the corresponding container, and a second pad, which is provided, on a working face thereof, with at least one suction port, for a removable retention of the second end of the safety strip, said second pad being able to move to oscillate with respect to said first pad about a rotation axis in order to allow said second pad to remove the second end of the safety strip from the retention head that acts on the corresponding container and to move the second end of the safety strip to adhere to a second lateral portion of the corresponding container, which is arranged on a side opposite to said first lateral portion, wherein the at least one application assembly comprises a suction device which is connected to the at least one suction port of the second pad;
wherein the second pad of the at least one application assembly is supported by a lever element which is connected rotatably to a supporting body, which is configured to move, with respect to a fixed structure of said application station, by means of an oscillation shaft which forms, with an axis thereof, said rotation axis, wherein at least one air feeding channel is extended, with at least one portion thereof, along the axis of said oscillation shaft.

Dependencies are inferred from the claim text.
