An apparatus for sealing an open end of a package comprises a first longitudinally extending sealing jaw, bearing mounted on a first eccentric shaft rotatable around a first rotational axis, and a second longitudinally extending sealing jaw, bearing mounted on a second eccentric shaft rotatable around a second rotational axis, the second sealing jaw being parallel with the first sealing jaw. At least one motor drives rotation around the first and second rotational axis in opposite directions, wherein the first and the second sealing jaws oppose each other, and are allowed to oscillate between sealing and open positions by moving towards and away from each other. A first and second transversally extending guiding bar cooperate with the first and second eccentric shaft via guiding pins running in guiding grooves, such that transverse play between the first and the second eccentric shaft and the first and second sealing jaw is allowed.

A bag (100) suitable for packaging fruit and vegetable products (2) comprising a casing (103) capable of housing the products to be packaged and at least one first band (104) and one second band (105) each arranged on the outer face of the casing so as to seal said casing, the first band (104) being joined to the casing only at its ends (104a, 104b) forming a handle (106) and the second band (105) joined along the length thereof to the associated face of the casing, forming a stable bottom (105c). A station (1) for producing this bag (100) comprises an expansion device (4) of tubular material comprising an upper expansion body (4a) and a lower expansion body (4b) mechanically linked to each other with a capacity for movement of one with respect to the other and that cooperate with welding groups.

Two workpieces 30, 40 are joined by means of ultrasound. First, a workpiece 30 with at least one energy direction sensor 31 and a second workpiece 40 are provided. The workpieces are brought into contact with each other in such a way that the energy direction sensor 31 comes into contact with a first surface 41 of the second workpiece 40. Ultrasonic vibrations are then introduced into one of the workpieces 40 via a working surface 11 of a sonotrode 10. A sonotrode 10 is used, which has a contour with contact lines 12 on the working surface 11. The sonotrode 10 is positioned with respect to the first workpiece 30 in such a way that the contact lines 12 run transversely to the energy direction generator 31.

A form fill seal apparatus for forming and filling a plurality of bags with a product having a tube formation assembly forming a tubular film, a bag forming assembly configured to form transverse seals and to cut the tubular film to form bags. A product delivery system is provided to deliver product from a positive displacement pump to a product delivery tube. A control system is structurally configured to direct the positive displacement pump to operate in two different modes, a first, continuous operating mode and a second, dosing operating mode. A method of filling is likewise disclosed.

An apparatus for sealing the top of a package for a food product is disclosed. The apparatus comprises a pair of oppositely disposed first and second sealing jaws configured for reversibly engaging each other over the top of the package, at least one wedge on the first sealing jaw configured for contacting a first top portion of the package to form a first gable panel, a key on the second sealing jaw configured for contacting a second top portion of the package to form a second gable panel, at least one lug on the key configured for reducing skewing of the package prior to sealing, and a rubber dolly on either the first or the second sealing jaw, the rubber dolly and the opposing sealing jaw being configured to form and seal a fin between the rubber dolly and the opposing sealing jaw thereby sealing the top of the package. A system for forming, filling, and sealing a package containing a food product comprising the apparatus is also disclosed.

A flexible sealing tube is described that is adapted to be installed in and extend along a bore in the ground for use in a system for exchanging of energy with the ground. The flexible sealing tube has a first tube end to be installed at an inner part of said bore, and the flexible sealing tube is closed in the first tube end. The flexible sealing tube also has a first channel and a second channel extending in a longitudinal direction (L) of the flexible sealing tube, the first and second channels being in fluid connection with each other. The first and second channels are formed by the flexible sealing tube.

The present invention relates to an apparatus and a method of folding a pouch case of a battery cell, and more particularly, to an apparatus and a method of folding a pouch case of a battery cell capable of preventing a meandering in a folding process and reducing non-uniformity of a folding amount by forming a pre-folding line on a pouch wing and folding the pouch wing on the basis of the pre-folding line.

An apparatus for heat-sealing a lidding film (2) to a supporting element (3), comprising a movement track (5), which extends between an infeed zone and an outfeed zone, a conveying unit (8) and a heat-sealing device (6) which is fitted along the movement track (5), the device (6) comprising a supporting unit (10) and a closing unit (11) which are movable between a home position in which they are at a distance from each other and an operating position in which they are coupled to clamp, in use, the lidding film (2) and a supporting element (3); wherein the conveying unit (8) is configured to support the supporting element (3) and to move and is associable with the movement track (5) for moving on it; the conveying unit (8) comprising one or more active portions (12) which are configured to support the supporting element (3) from below and to couple to the supporting unit (10) to define with it a clamping unit for clamping the supporting element (3) against the closing unit (11).
