摘要:
An in-line continuous feed sleeve labeling machine labels containers, such as beverage containers, in an in-line fashion maintaining the elevation of the containers during their linear transport. The in-line continuous feed sleeve labeling machine of the present invention receives bottles in flood feeder or linear fashion. A timing screw or the like properly separates, and both spatially and temporally disposes, the containers for sleeving. The timing screw propels the containers onto a pedestal system. The pedestals of the pedestal system maintain their horizontal nature due to offset pivotable attachments to the track system upon which they travel. A sheet of film is unspooled from an unwind roll and passed through a tube forming apparatus that overlaps the edges of the film. The overlapping edges completing the tube enclosure are connected using ultrasonic welding or the like. The sleeve is then passed to an iris carrier. In coordinated fashion with the travel of the pedestal system, iris carriers carrying sleeves upon articulating radial arms descend upon the bottles. Once the label sleeve has reached the appropriate point (generally adjacent to the central portion of the bottle), the iris carrier allows the label sleeve to engage the central portion of the bottle. Frictional attachment or otherwise allows the finger rods of the iris carrier to pull away from the sleeve as the iris carrier continues to descend down towards the pedestal. The sleeve then becomes attached to or engaged by the bottle until the finger rods of the iris carrier free themselves from the sleeve label. A container stabilizer may provide lateral bottle support and aid the ensleevement process. The finger rods then dilate to better disengage the bottle as the iris carrier ascends up and away from the bottle. The bottle is then transported to an exit conveyor having been properly sleeved, while the iris carrier returns to transport another sleeve.

A packaging machine for forming pouches from a web of material having web tension control. A second pair of infeed rolls allows web tension through a sealing section to be controlled. An unwind reel is power-driven according to downstream web demand to thereby minimize tension spikes through the infeed section. The power unwind further minimizes the amount of festoon area needed. An entire packaging machine may be provided using modules. The registration-related operations of each section are independently controlled so that each module need only coordinate input and/or output speeds with interfacing sections.

The present invention includes methods, an apparatus and a system in which reclosable bags and components thereof are formed. The reclosable bags are made from base web material that has transversely applied fastener tape segments thereon. The web material is used in a vertical form, fill and seal bag forming method. The method includes the steps of supplying a continuous strip of tape, having first and second closure elements sealed thereon. The first and second closure elements have respectively a pair of male profiles and a pair of female or u-shaped elements thereon, each shaped for interlocking with the other. A thickened sealing bridge between the male elements and a second thickened sealing bridge between the female elements allows precise sealing of the fastener element to fastener tape or to the bag walls as desired. It also facilitates keeping the profiles interlocked.

A process produces a tubular body with at least one dividing wall extending across its length and forming longitudinal chambers disposed next to each other. A foil strip is used whereby a dividing-wall strip or a section of dividing-wall strip is cut to length and is fastened at its lateral outer edges on the foil strip or section of the foil strip, with parallel alignment with the foil strip or section of foil strip. The lateral edges of the foil strip or section of foil strip are then joined with each other thereby either directly forming a tubular body or forming an endless tube, from which tubular bodies are then cut to length. The tube is then solidly joined with a tube head having a dividing bridge conforming to the arrangement of the dividing wall in the tubular body. The tube head has a dispensing aperture closable by a closure.

A hose is made by continuously transporting a first strip of plastic film through an assembly station. One or more contiguous molten beads are deposited onto a central region of the film. The beads are formed into a flow regulating passage defined by side walls. A second strip of plastic film, which is narrower than the first strip of film, is sealed to the side walls while molten to form a flow regulating passage between the sidewalls and the first and second strips of film. Inlets to the flow regulating passage and outlets from the flow regulating passage are formed at spaced intervals along the hose. The first strip of film is longitudinally folded to overlap the margins and the overlapping margins are sealed to complete the hose.

A drip irrigation tape consists of a strip of flexible material having an elongated, indented channel formed along a first side edge, the channel being of serpentine configuration, the strip being folded lengthwise so that the side edges overlap to form a first conduit, and the opposite side edges being joined together at least along spaced seal lines along opposite edges of the channel to define a secondary conduit. Inlets and outlets are provided along the length of the channel. A method for manufacturing the tape includes the steps of forming the indented channel on a mandrel before sealing the overlapping edges of the strip together by heat sealing or ultrasonic welding.

The present invention provides a reinforced plastic laminate structure comprising an elongated reinforcing material that is encapsulated by an extruded plastic material that forms a continuous structure around the reinforcing material. The present invention contemplates methods of extruding a tube of plastic material while simultaneously introducing a reinforcing material within the interior of the tube. Thereafter, the tube is flattened so that the interior wall of the tube comes in contact with the reinforcing material to encapsulate the reinforcing material in a continuous structure. The reinforced plastic laminate sheet is made from an apparatus an extruding machine for extruding plastic with an annular die and opening for the extruding tubing. Attached to the extruding machine is a mandrel which feeds a reinforcing material into the center of the annular opening. Pressure rollers flatten the tubing after it exits from the annular die. The reinforcing plastic material may be formed into a variety of useful products where increased strength is required. The ease of manufacture provides a cost advantage over conventional construction materials.

A method and an apparatus for heat welding a butt seam on a tube of packaging material, in which the welding heat is generated by applying a high-frequency alternating electromagnetic field of a pair of induction coils. To prevent current arcing at the cut edges of a metal inlay of the packaging material in the vicinity of the abutting edges of a sheet of packaging material, the edges are guided spaced apart from one another by a predetermined distance. To this end, the apparatus has a separating blade, which in the operative range of the electromagnetic alternating field protrudes in between the abutting edges of the sheet of packaging material and between the induction coils.

A method of manufacturing a porous tetrafluoroethylene tube comprises forming a sheet of tetrafluoroethylene containing a lubricant, winding it into a tubular shape, wrapping reinforcing material about the tubular shape to form a tubular product, rolling the tubular product so that it may have a uniform wall thickness, preheating the tubular product at a temperature lower than 327.degree. C., stretching the tubular product longitudinally, and heating it at a temperature higher than 327.degree. C., while holding it in its stretched position. The method may also be used to manufacture a tube containing 15 to 95% by weight of a filler.
