A device for assembling plastic objects including caps for coupling to base support at least partially counter-shaped to the cap. The device includes at least part of an assembly line defining assembly path and assembly plane including the assembly path and plurality of spindles moveable along the assembly path by an apparatus and configured to controlledly pick up the caps, the spindles position and push the caps onto the base supports along the assembly path; positioning apparatus including first and second detectors, controller with auxiliary control system to translate and rotate spindles along directions perpendicular to assembly path and plane and third encoder to detect spindle orientation relative to assembly path. First detector to detect first orientation, second detector to detect second orientation and controller to detect first orientation and second orientation by detectors and operate auxiliary control system to align base support and cap.

A method and apparatus for manufacturing a tampon packaging where the packaging is manufactured separately from the tampon. A first transversal end is overlapped with a second transversal end of a strip of heat-sealable film. The first transversal end is heat sealed to the second transversal end of the heat-sealable film, thereby forming a tube of film.

A station for sealing thermoformed containers for a packaging line and a method for sealing the containers includes a sealing carousel which rotates continuously about a central axis and includes sealing heads which are radially spaced apart from said central axis. Each sealing head is adapted to receive at least one container to be sealed at a first, input, peripheral region, which is outside the sealing carousel; receive at least one closing seal at a second, input, peripheral region, which is outside the sealing carousel; and hold the closing seal and the container during the rotation of the sealing carousel and couple them together.

The station further releases the container complete with the closing seal at a third, output, peripheral region, which is outside the sealing carousel and angularly spaced from the first and from the second region.

A system for assembling a container and closure comprising an expanding collet which has a plurality of pivoting collet segments, each configured to simultaneously pivot radially outward about a pivot point and comprising. The collet comprises a lip that is engagable with the rim of the open end of the container and an angled tip positioned radially inward from the lip and shaped to press a countersink portion of the closure against an interior wall of the container as the collet segments pivot radially outward. As the container and the chuck are brought together, the rim engages with the lips of the collet segments and causes the angled tips of the collet segments to pivot outward toward the interior wall of the container, thereby pushing the countersink portion of the closure against the interior wall of the container.

An apparatus for the transverse welding of a tape traveling in a machine direction, comprising: a stationary structure, a rotary structure rotatable with respect to the stationary structure about a rotation axis perpendicular to said machine direction, a plurality of welding units carried by said rotary structure and spaced apart in a circumferential direction, wherein each of said welding units comprises an inner welding element fixed relative to the rotary structure and an outer welding element cyclically movable with respect to the rotary structure between a release position and an operative position, and vice versa, wherein each of said outer welding elements during the movement from said release position to said operative position, and vice versa, performs an angular rotation movement about a respective radial axis perpendicular to said rotation axis, and a linear translation movement along said radial axis.

The invention pertains to a method for manufacturing a tampon packaging (24), comprising the steps of: a) wrapping a strip of heat-sealable film (23) around a holding means (1, 18), whereby a first transversal end (27) of said strip overlaps with a second transversal end (28) of said strip; b) heat sealing said first transversal end (27) to said second transversal end (28), thereby forming a tube of film, and c) removing said tube of film from said holding means, thereby obtaining a tampon packaging, characterized in that said heat sealing step (b) is performed at least partly during a combined movement of said holding means (1, 18) and said strip (23). The invention further pertains to related apparatuses, systems of tampon and tampon packaging and methods for manufacturing a packaged tampon.

A rotary welding device which includes a rotary part rotating about its axis of rotation, one or more supporting elements for supporting a continuous strip, specifically a strip of nappies, supported by the rotary part, and a plurality of welding units, mounted on the rotary part, for welding the continuous strip; each welding unit is configured to pass from a non-operating position to an operating position and vice versa; each welding unit includes a respective welding tip and a respective anvil element which is movable relative to the welding tip; each welding unit includes respective first movement means configured to drive the anvil element in rotation relative to the welding tip from an initial position, where the anvil element is angularly spaced from the welding tip, to a final position, where the surface of the welding tip and the surface of the anvil element are parallel and aligned with each other along the same axis, and vice versa.

An ultrasonic welding system and method for making welds on a strip made of polymeric material. The system includes a supporting structure, N welding equipment mounted thereon, and a processor. Each N welding equipment includes a pair of welding heads made of a sonotrode, including a sonotrode welding surface, and an anvil, including an anvil welding surface. One of the two welding heads is movable with respect to the other between a non-operating position and a welding position. A control member is operatively associated with the sonotrode and configured to vibrate the sonotrode at a nominal ultrasonic vibration frequency and to detect a current value of the vibration frequency. A vibration sensor is mounted on the movable welding head. The processor monitors the alignment condition between the sonotrode welding surface and the anvil welding surface by cooperating with the control member and with the vibration sensor.
