A method for providing an inductive sealing bar, comprises providing a conductive coil having at least one heating zone, embedding the coil in a supportive body such that the supportive body covers the entire coil along at least some part of the length of the at least one heating zone; and providing a sealing surface of the sealing bar by planarizing the coil and the supportive body such that the coil is exposed along the entire length of said at least one heating zone. The invention also relates to a sealing bar manufactured according to the method.

Sealing bar

An induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products, comprising: at least one first inductor which comprises, in turn, a first active surface adapted to be arranged on the side of packaging material and to heat-seal it; and a member made of plastic material; first active surface is covered by the member made of plastic material adapted to cooperate with the packaging material during its heat-sealing.

Folding unit for forming sealed packages of pourable food products

An induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products and fed in a first direction, the sealing device having an inductor device which interacts with the packaging material by at least one active surface; a supporting body made of heat-conducting material and housing the inductor device; an insert made of magnetic flux-concentrating material and housed in the supporting body; and a member made of plastic material, and having at least a first portion interposed, in the first direction, between the supporting body and the insert so as to be at least partly surrounded by the supporting body.

The invention relates to a counter element () being adapted to apply a pressure to a first portion of a packaging material in association with heating of the packaging material in order to seal the first portion of the packaging material to a second portion of the packaging material. The element () being provided with an abutment surface () adapted to at least abut said first portion of the packaging material. The abutment surface () is provided with a plurality of indentations () adapted to entrap fluid or gas present in the vicinity of the abutment surface () and the first portion of the packaging material. The inventions also relates to a method of providing a counter element () as described above.
