摘要:
A sealing element (9) for heat sealing packaging material (4) for producing sealed packages comprises a heating element (13) arranged to heat-seal said packaging material (4) so as to form said sealed packages and a groove (17) arranged to be engaged by a cutting element (18) carried by a counter-sealing element (10) interacting with said sealing element (9) during a cutting operation in which a sealed package is separated from a portion of said packaging material (4), wherein said sealing element (9) further comprises a resilient element (25) received within said groove (17) so as to prevent clogging particles from entering into said groove (17).
摘要:
An improved induction sealing device (300) is presented. The device (300) comprises a main body (302), a magnetic field concentrator (306) held in said main body (302) and a conductive element (304). One or several protrusions (314a, 314b) of said magnetic field concentrator (306) cooperate with one or several indentations or openings (312a, 312b) in said main body (302) such that said magnetic field concentrator (306) and said main body (302) is securely bonded together.

An apparatus for capping a container (10) comprises: - a conveying device for conveying the container (10) along a path; - an applying head (23) for applying a lid (1) onto a neck (9) included in an opening device of the container (10); - a welding head (43) arranged downstream of the applying head (23), the welding head (43) comprising a welding element (51) for welding the lid (1) to the opening device.
摘要:
A method of applying a lid (1) onto a neck (9) of a container (10), the lid (1) having a side wall (3) extending around an axis and an end wall (2) extending transversely to said axis, comprises the following steps: - positioning the lid (1) onto the neck (9); - exerting on the end wall (2) a force directed towards the container (10), so as to level the lid (1) on the neck (9); - screwing the lid (1) onto the neck (9) by rotating the lid (1) in a screwing direction.
摘要:
A forming member for controlling the volume of packs (2) of pourable food products formed from a tube (14) of packaging material, said tube (14) comprising a longitudinal seal (102) obtained by superimposing a first longitudinal edge (100) of said packaging material on a second longitudinal edge (101) of said packaging material and by sealing said first longitudinal edge (100) to said second longitudinal edge (101), wherein said forming member comprises a forming half-shell (71) having a forming wall arrangement (77) adapted to interact with said tube (14), and wherein said forming member further comprises a pushing element (80) associated to said forming wall arrangement (77) to push part of said food product out of said tube (14), said pushing element (80) having a grove (83) intended to receive at least a portion of said longitudinal seal (102) .
摘要:
There is described a sonotrode (81) for sealing an opening device (4, 4a) onto a hole (3) of a packaging material (5) destined to from a sealed package (2), comprising: a sealing surface (89) adapted to cooperate with a said packaging material (5) in order to seal opening device (4, 4a) to packaging material (5); a cavity (90) bounded by an opening (88) of sealing surface (89) and adapted to receive said opening device (4, 4a); and a ring (91) made in an elastomeric material, partially protruding inside said cavity (90), and adapted to center a first axis (A) of said opening device (4, 4a) on a second axis (B) of said sonotrode (81).
