Abstract
A welding unit for a machine for forming capsules having a pleated capsule body and a reinforcing element. The welding unit has a welding housing configured to accommodate the reinforcing element and the pleated capsule body coaxially during welding. The welder, preferably with fixed geometry, is coaxial with respect to the welding housing and configured to be inserted within the welding housing and to weld the reinforcing element to the pleated capsule body. The welding housing acts as a counter element for the welder during welding. The welding unit has elastic means coupled to the welding housing in such a way that said welding housing is elastically movable and/or elastically deformable by the thrust of the welder.
Claims20
A welding unit for a machine for forming capsules having a pleated capsule body and a reinforcing element, said welding unit comprising:
- a welding housing configured to accommodate said reinforcing element and said pleated capsule body coaxially during welding;
- a welder, preferably with fixed geometry, configured to be inserted coaxially with respect to said welding housing within said welding housing and to weld said reinforcing element to said pleated capsule body;
- wherein said welding housing acts as a counter element for said welder during welding;
- and
- wherein said welding unit further comprises:
- elastic means coupled to said welding housing in such a way that said welding housing is elastically movable and/or elastically deformable by a thrust of said welder.
Method for refurbishing a machine for forming capsules having a pleated capsule body and a reinforcing element, said machine comprising one or more welding units, each one of the welding units comprising:
- a welding housing configured to accommodate said reinforcing element and said pleated capsule body coaxially during welding;
- a welder, preferably with fixed geometry, configured to be inserted coaxially with respect to said welding housing within said welding housing and to weld said reinforcing element to said pleated capsule body,
- wherein said welding housing acts as a counter element for said welder during welding;
- and
- wherein the method comprises the following step:
- providing said welding housing with elastic means so that said welding housing is elastically movable and/or elastically deformable by the thrust of said welder.
A welding unit for a machine for forming capsules having a capsule body and a reinforcing element, the welding unit comprising:
- a welding housing having a cavity, the cavity with an opening configured to receive the reinforcing element and the capsule body;
- a welder having a distal end, the distal end of said welder configured to insert coaxially within the cavity of said welding housing during welding, wherein the capsule body and the reinforcing element are positioned between an exterior surface of said welder and an interior surface of said welding housing;
- and
- an elastic member biasing the interior surface of said welding housing against the exterior surface of said welder,
- whereby relative movement between said welding housing and said welder provide an internal diameter of the welding housing and an external diameter of the welder to coincide along a weld zone welding the capsule body to the reinforcing element.
