A process of manufacturing a down product comprises at least one bonding pattern line for the compartment separation without forming sewing holes by printing and drying a heat-reactive adhesive on the inner surface of an inner fabric, an optional mesh material and/or an outer fabric in a predetermined pattern, laminating said inner fabric, optional mesh material and/or outer fabric, and then high-frequency heating them under pressing with a pressing pattern the same as the printing pattern to bond the inner fabric, optional mesh material and outer fabric. Accordingly, it is possible to manufacture a down product having a bonding pattern line composed of a bonding line with excellent adhesiveness and durability and an aesthetically excellent pattern line with good clearness and finishing quality as well as to achieve a mass production of down products by mechanization and automation.

The present invention concerns an apparatus for ultrasonic processing of materials having an ultrasonic processing system comprising an ultrasound generator, a converter, a sonotrode and a counterpart tool and a feed unit with which the sonotrode and the counterpart tool can be moved towards each other or away from each other, wherein there is provided a force sensor with which the force that the ultrasonic processing system exerts on the materials to be processed can be measured. To provide a corresponding ultrasonic processing apparatus which allows a greater processing speed it is proposed according to the invention that the force sensor is a piezoelectric sensor whose output is converted into an electrical voltage by means of a charge amplifier and that there is provided a control device which either when the ultrasonic processing is not performing material processing short-circuits the piezoelectric sensor or adds a time-varying force compensation unit to the value measured by the piezoelectric sensor.

The present invention is intended to prevent cutting of the resilient and elastic members by a welding process. The foregoing issue is solved by passing a first sheet layer, a second sheet layer, and elongated resilient and elastic members continuously disposed in an MD direction between the two sheet layers, between a first roll with joint convex parts provided at circumferential intervals on an outer peripheral surface and a second roll opposed to the first roll, and pressurizing and heating the first sheet layer and the second sheet layer to form sheet joined sections by welding the first sheet layer and the second sheet layer in such a manner as to cross the resilient and elastic members and have MD-direction intervals therebetween, wherein circumferentially continuous grooves are formed on a pressurization surface of the second roll, passage sections of the resilient and elastic members are pressurized and heated in positions including the grooves of the second roll, and non-passage sections of the resilient and elastic members are pressurized and heated in positions not including the grooves of the second roll.

Disclosed embodiments relate to an induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products. In some embodiments, the sealing device includes: an inductor device which interacts with said packaging material by means of at least one active surface; a flux-concentrating insert; and a supporting body made of heat-conducting material and housing said inductor device and said flux-concentrating insert, wherein said flux concentrating insert is made by a magnetic compound of a polymer and soft magnetic particles; and said flux concentrating insert interacts with said packaging material via at least one interactive surface.

A method for the production and filling of an application package for a liquid pharmaceutical product. A thermoforming film made of thermoplastics laminated together is heated in order to plasticize the thermoforming film at least in partial areas. The plasticized areas are thermoformed in a mold in order to form a chamber for the liquid pharmaceutical product and a tube-shaped application duct opening into this chamber, with the chamber and the application duct being enclosed by a non-thermoformed, essentially flat bonding area of the thermoforming film. The liquid pharmaceutical product is filled into the chamber, and the chamber and the application duct are sealed by covering the thermoformed and filled thermoforming film with an essentially flat covering film. The covering film is directly bonded to the bonding area of the thermoforming film by thermal ring sealing, enclosing the chamber and the application duct.

A sealing element for heat sealing packaging material for producing sealed packages comprises a heating element arranged to heat-seal the packaging material so as to form the sealed packages and a groove arranged to be engaged by a cutting element carried by a counter-sealing element interacting with the sealing element during a cutting operation in which a sealed package is separated from a portion of the packaging material, wherein the sealing element further comprises a resilient element received within the groove so as to prevent clogging particles from entering into the groove.

Provided is a device and method for butt-splicing strip members for tire components, having a first clamp and a second clamp arranged for clamping a first end of a first strip member and a second end of a second strip member, respectively, wherein at least one of the first clamp and the second clamp is movable along a butt-splice direction into a butt-splicing position opposite to the other of the first clamp and the second clamp for butt-splicing the ends, wherein the first clamp includes a first upper clamp member and a first lower clamp member, wherein the second clamp includes a second upper clamp member and a second lower clamp member, wherein the first lower clamp member projects beyond the first upper clamp member over a first overlap distance and wherein the second upper clamp member projects beyond the second lower clamp member over a second overlap distance.

A sheet filter membrane is arranged on a surface of a filter plate of a thermoplastic resin, and a plurality of projections provided in a hot plate is pressed against the filter plate above a periphery of the filter membrane with different timing for each of the projections to abut on the filter membrane. A plurality of recessed bonding portions with different depths are thus formed in the filter plate, and the filter membrane is bonded to the filter plate by heat welding in each of the recessed bonding portions. Sealing is therefore provided between the filter membrane and the filter plate along the periphery of the filter membrane.

The present invention provides an apparatus for producing and putting on gloves capable of producing gloves that fit an individual hand shape and also putting the glove on the hands, and a method for producing and putting on gloves. The apparatus for producing and putting on gloves comprises welding and cutting means which welds and cuts a first elastic film and a second elastic film at a position on the outer side of a contour of a user's hand in a state in which the user's hand is sandwiched between the first elastic film and the second elastic film.

A method and a device are disclosed for making thin plastic films having two or more layers, which are subdivided and separated in the form of tubular bags for portioned reception of different products, wherein the plastic films are provided with welding seams running substantially transversely to the longitudinal direction with predetermined spacing between one another to form bag-like containers, and the containers are separated from one another by a cutting or separating process, the method being characterized by the steps: a) welding the films with predetermined spacing by means of an ultrasound welding process, maintaining a defined, film-dependent distance between a processing tool and a counter tool while welding; and b) separating the tubular bags welded in this way by means of a mechanical cutting process, with or without reduced ultrasound excitation at the point of the respective weld seams.
