A welding head comprises a welding element for welding a lid to an opening device of a container, a supporting body for supporting the welding element and a compensating device for compensating a possible mutual mispositioning of the welding element and the lid during welding of the lid to the opening device, the compensating device being interposed between the supporting body and the welding element, the compensating device comprising a planar spring arrangement provided with at least one planar spring element having a first member and a second member mutually connected by deformable elements.

Welding head

A method of applying a lid () onto a neck () of a container (), the lid () having a side wall () extending around an axis and an end wall () extending transversely to said axis, comprises the following steps: &#x2014;positioning the lid () onto the neck (); &#x2014;exerting on the end wall () a force directed towards the container (), so as to level the lid () on the neck (); &#x2014;screwing the lid () onto the neck () by rotating the lid () in a screwing direction.

Method of, and an applying head for, applying a lid onto a container

A welding head comprises a welding element () for welding a lid () to an opening device of a container (). The welding head () further comprises a 5 compensating device () operable for compensating a misalignment between the welding element () and the lid (), thereby centering the welding element () relative to the lid ().

An apparatus for capping a container () comprises: &#x2014;a conveying device for conveying the container () along a path; &#x2014;an applying head () for applying a lid () onto a neck () included in an opening device of the container (); &#x2014;a welding head () arranged downstream of the applying head (), the welding head () comprising a welding element () for welding the lid () to the opening device.

Apparatus for capping a container

An applying unit for applying lids to necks of containers may be provided. The applying unit may include a conveying device configured to advance the containers along a path in an advancement direction; a group of applying heads, each applying head configured to screw a lid onto a corresponding neck; and a movement device configured to move the group of applying heads along the advancement direction, so that each applying head may be coupled to a corresponding neck along a portion of the path. The movement device may be configured to act on a common support element configured to support the applying heads of the group, so as to synchronously move the applying heads along the advancement direction.

Applying unit for applying a lid onto a container

A unit for the application of opening devices on respective sealed first packages of food products, comprising: at least one first gripping device configured to receive, in use, a relative opening device and movable along a first path; the first path comprising a first stretch in which the opening device is applied onto the package; a first track; a first transfer element, which is operatively connected to the first gripping device; and at least one second transfer element; the first transfer element is movable along the first track and is movable relative to and independently of second transfer element.
