摘要:
The present invention relates to a thermal pressure welding apparatus for the waist of incontinent pants and training pants and a thermal pressure welding method. The apparatus can thermal pressure weld the waist of incontinent pants and training pants consists of multiple layers of non-woven fabric in a fast, accurate and secure manner. An upper synchronous transmission mechanism and a lower synchronous transmission mechanism are disposed vertically opposed, by means of a shaft, on a side of a vertical frame. The upper synchronous transmission surface of the upper synchronous transmission mechanism and the synchronous transmission surface of the lower synchronous transmission mechanism are opposed. A plurality of toothed pressing blocks are spacedly opposed on the upper synchronous transmission surface and the lower synchronous transmission surface respectively. An electrothermal tube inside the toothed pressing block is connected to supply lines in a conductive ring through extendable wires and wiring flanges, which conductive ring is rotated synchronously with the upper synchronous transmission mechanism and the lower synchronous transmission mechanism. The plane rails moving up and down are positioned on the inner sides of the synchronous transmission surfaces of the upper synchronous transmission mechanism and the lower synchronous transmission mechanism respectively and the rail surfaces of the plane rails are vertically opposed.

Provided herein is a liquid-filled, non-reclosable tetrahedral or pillow-shaped packaging container having a longitudinal fin seal and a pair of transverse seals. In the case of tetrahedral packages, the transverse seals are perpendicular to one another. Also provided herein is an apparatus for the formation of such fin seals as part of a continuous packaging and filling operation. A third aspect of the apparatus of the present disclosure is the development of a heated jaw that exhibits consistent heating across the jaw face. Yet another feature of the apparatus of the present disclosure is provided in a modified, closed-loop electrical system for real-time monitoring and adjustment of the temperatures of the heated jaws, as they are moving.

Apparatus for forming a bag assembly from a tube and a tubular flexible membrane operates in accordance with a four step process. This process includes the steps of clamping the tube within an open end of the membrane, injecting liquid adhesive into the open end of the membrane, clamping the membrane and tube where the adhesive was injected, and heating and curing the assembly.

A method of and apparatus for continuously making liquid filled packages wherein a tube is formed from a web, and, having been filled with liquid, is passed round a first turntable to be pre-shaped into packages and to shape first side walls of the packages. The tube is transversely sealed an cut on the first turntable and then passed round a second turntable to shape second, opposite, side walls of the packages.

Embodiments herein include a system for joining components. The system can include a rotating base platform, a plurality of receptacles mounted to the base platform, and a rotating sonotrode platform. A plurality of sonotrodes are mounted to the sonotrode platform. Each sonotrode can correspond to a receptacle. Each sonotrode can move in a reciprocating motion between a release position distant from a corresponding receptacle and a compressing position proximal to the corresponding receptacle. The compressing position occurs at a first angular position of the sonotrode platform. Each sonotrode is energized at the compressing position.

The end folds of cellophane wrappings applied to products advancing along a given feed direction are heat-sealed by a device appearing substantially as a feed channel. The channel coincides with the feed direction and is compassed at least on one side by a conveyor belt extending parallel with a fixed path followed by the products and equipped with a succession of heated pads positioned to enter into contact with selected portions of the end folds; during their passage along the path, only the pads occupying one or more limited sections of the feed channel will be heated, according to the amount of thermal energy that needs effectively to be transferred to the pads in order to seal the folds.

A bottle carrying handle including a substantially irregular elongated body which is tubular-shape configurated at its middle part, the body having at least two ends, each end defining a hook carrying portion formed by a planar surface which is cut in a "U" shape configuration. The cut forms two supporting legs and each leg includes a bottle neck retainer. An apparatus for manufacturing the handle includes a plurality of moulds and countermoulds, each mould includes a "U" shaped central cavity and each leg of the "U" has a "U" shaped recess. One of the legs includes an "L" shaped recess which is aligned with respective projections provided in the associated countermould of the set, these projections are spaced apart by small spaces. Each countermould includes a block having a "U" shaped central cavity aligned with the cavity of the mould and each leg of the "U" includes horizontal "U" shaped projections aligned with the respective "U" recesses formed in the corresponding leg of the associated "U" shaped cavity of the mould.
摘要:
Apparatus for continuously producing seals in tube-shaped plastics film material, comprising means for supplying the web of material, at least one heating beam travelling along with the web and subsequently returning, means for keeping the web mechanically tension-free at the location where it is warm, means for keeping the heated film layers one against the other up to a pressing station, said pressing station comprising two rollers at least one of which is provided with cooling means, and means for discharging the web. A plurality of heating beams being provided which are interconnected by flexible and longitudinally adjustable means such as belts so as to form an endless loop which is guided over and driven by appropriate adjustable tensioning rollers.
