Abstract:
A sealing element (15) for heat sealing packaging material for producing sealed packages (3) of food products which are pourable within a tube (2) of packaging material; sealing element (15) comprises heating means (20, 21) adapted to heat-seal the packaging material at spaced cross sections of tube (2) so as to form a plurality of sealed packages (3), and a groove (60) which may be engaged by a cutting element (62) carried by a counter sealing element (16) during a cutting operation in which a sealed package (3) is separated from tube (2); sealing element (15) comprises at least a slot (70) which extends between groove (60) and a first outer wall (53, 54) of sealing element (15).
Abstract:
An apparatus for attaching a tube segment to a bag by fusing them together in an aseptic form, fill and seal operation is provided. The apparatus includes a sterile processing chamber in which a sterilized tube segment and a pair of opposing wall portions of a flexible bag are to be located. The sterilized tube segment has an open end which is to be placed in communication with an interior space of the bag. A tube inserter is at least partially located within the processing chamber and arranged to grip the tube segment and place the tube segment between the wall portions of the bag. At least one member is provided for fusing the tube segment between the wall portions of the bag so that the open end of the tube segment is in communication with the interior space in the bag. A bag formed using the apparatus and a method of forming the fused tube-on-bag are also provided.
Abstract:
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 (8) further comprises a resilient element (25) received within said groove (17) so as to prevent clogging particles from entering into said groove (17).
Abstract:
An irrigation pipe (12) with holes is provided. The pipe is, at least in the area of each hole, multilayered. At least top (152a) and bottom (152b) layers of the pipe (12) are made of a water-repellant material, and an inner layer (154) of the pipe (12) is made of a porous material. The hole is defined by a cut surface of the pipe wall. The cut surface comprises a seal, which covers at least the inner layer (154). Each layer (152a, 152b, 154) may be bonded to adjacent layers.

Abstract:
The valve is comprised of a strip (1) on which are welded two coplanar strips (3, 4) separated by an opening (5). In order to fabricate the valve, a web (11) is used on which are welded two bands (12, 13), separated by a gap (5). The resulting valve (16) is welded onto a sheet (17) which is part of the inflatable body, is provided with an orifice (19) in registration with the opening (5) of the valve. Then, a second sheet (21) forming the inflatable body is welded to the first sheet. Said process provides for the production of a single-inlet double valve.
Abstract:
An improved induction sealing device is presented. The device comprises a main body (302, 402a, 402b), a magnetic field concentrator (306, 406a, 406b) held in the main body and a conductive element (304, 404a, 404b) also held in the main body (302, 402a, 402b). The magnetic field concentrator (306, 406a, 406b) is injection molded in said main body (302, 402a, 402b). For this purpose the main body (302, 402a, 402b) is provided with at least one hole (312a, 312b) to gate material for forming said magnetic field concentrator (306, 406a, 406b) into an interior of said main body (302, 402a, 402b).
