A lining drum which has a tubular body having open ends, an inlet for compressed air and an outlet for liner is disclosed. The lining drum has end pieces removably attached to the tubular body for closing the open ends of the tubular body, a rotatable shaft inside the tubular body and a crank for rotating the shaft. An elastic fastener has a first end in operative engagement with the tubular body and a second end in operative engagement with the end piece. The second end is opposite the first end. The end piece is movable between a closed position and an open position by extending the elastic fastener against an elastic biasing force of the elastic fastener. The end piece and the tubular body has a gap defined therebetween when the end piece is in the open position.

A multipurpose spatula which has a separable pressing member on the outer surface of a body thereof. The pressing member is rotatable as required to allow a side surface thereof to be located on the end of one side pressing piece. This minimizes the occurrence of scratches on sheets attached to advertising signs and tables, etc. and also promotes user conveniences.

The invention relates to a device for welding a connection region of a film to a connection part having an axial direction. In the case of conventional devices, there is the risk of steep workpiece edges causing uncontrolled weak spots in the film and in the weld seam. According to the invention, the film is extended in a controlled manner such that the film has a length reserve. The film is extended in such a way that the film has a deformation cross-section that runs out such that the deformation is not visible on the final product. In this connection, the invention further relates to a use of a film, to a method for welding, to a method for producing bags, to a system for producing bags, and to a bag.

A sealing tool for sealing a flexible packaging material comprises a first jaw including a first jaw surface and a second jaw including a second jaw surface with the respective jaw surfaces arranged opposite to each other. The first jaw surface includes a groove and the second jaw surface includes a ridge and wherein the groove on the first jaw surface and the ridge on the second jaw surface are designed to mate with each other when the jaw surfaces are moved towards each other. The groove on the first jaw surface has a groove bottom featuring a curved cross-section and the ridge has a ridge top featuring a curved cross-section.

A system holds a roll of film that includes a core and film wound around the core. The system includes a rod having an outer diameter that is smaller than an inner diameter of the core, a proximal wing located on the rod and configured to rotate about the rod, and a distal wing located on the rod and configured to rotate about the rod. Each of the proximal and distal wings includes contact surfaces configured to contact diametrically-opposed locations on a side of an inner surface of the core and non-contact surfaces that span between the contact surfaces of the wing. The non-contact surfaces of the wings do not contact the core if the core has a cylindrical shape. The distal wing is capable of rotating around the rod independently of the proximal wing.

A lining drum which has a tubular body having open ends, an inlet for compressed air and an outlet for liner is disclosed. The lining drum has end pieces removably attached to the tubular body for closing the open ends of the tubular body, a rotatable shaft inside the tubular body and a crank for rotating the shaft. The end piece has a spring-loaded flange mounting, wherein bias of springs pushes the flange mounting towards the tubular body and a closed position of the flange mounting, and air pressure inside the lining drum pushes the flange mounting away from the tubular body and towards an open position of the flange mounting.

Methods are provided for fabricating electrochromic devices that mitigate formation of short circuits under a top bus bar without predetermining where top bus bars will be applied on the device. Devices fabricated using such methods may be deactivated under the top bus bar, or may include active material under the top bus bar. Methods of fabricating devices with active material under a top bus bar include depositing a modified top bus bar, fabricating self-healing layers in the electrochromic device, and modifying a top transparent conductive layer of the device prior to applying bus bars.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

A system for opening and closing a mixing manifold includes a drive motor, a cam plate, and a valving rod connector. The drive motor imparts movement in first and second directions. Movement imparted in the first direction causes the cam plate to move linearly in a third direction and movement imparted in the second direction causes the cam plate to move linearly in a fourth direction. Movement of the cam plate in the third direction causes the valving rod connector to move linearly in a fifth direction and movement of the cam plate in the fourth direction causes the valving rod connector to move linearly in a sixth direction. Movement of the valving rod connector in the fifth direction causes retraction of a valving rod of the mixing manifold and movement of the valving rod connector in the sixth direction causes extension of the valving rod.

A product made by a method for bonding fibers that includes providing a first fiber layer and a second fiber layer positioned below the first fiber layer to bond the first fiber layer with the second fiber layer. The method may also include providing a first additive layer. The first additive layer is located between the first fiber layer and the second fiber layer. Then, the method may further include activating the first additive layer by directing energy at the first additive layer.
