Abstract: Paper from a roll or other supply is processed by an in-line magazine publishing and/or assembly system. The processing sequence includes printing pages of the magazine in predetermined places on the paper, laying down patterns of glue in other places of the paper, cutting a pattern of perforations and slits in the paper related to the glue pattern, cutting the paper into two sections, one of which is folded forming the pages of the magazine. The other section is folded forming the magazine cover, including pockets defined by the glue pattern. One pocket takes the form of a tear-out remittance envelope, the other pocket taking the form of a tear-out invoice sheet. A window in the cover exposes and uses the name and address on the invoice for the magazine mailing address.

Abstract: A tape dispenser for taping a product. A lever unit is pivotally mounted in a frame, with a support for a roll of tape. A cutter head and a tape roller are carried by the lever unit, with the tape following a path from the initial roll of tape over the roller to the cutter head, with the adhesive side of the tape exposed and away from the components of the dispenser. The cutter head is pivotally mounted on the lever unit and a linkage or a rack and pinion provides for pivoting the cutter head from a tab folding position to a cutting position as tape is pulled from the roll, over the roller and onto the product. The taped product is cut from the remainder of the tape at the cutter thereby releasing the pulling force on the lever unit which returns to its original position producing slack in the tape which is folded over to produce the desired tab.

Abstract: A hand-held wallpaper applicator for supporting and applying sheet material to a wall or other surface comprises a hand held support member having a hand grip portion and a flat generally rectangular base portion with an elongate separable roller assembly rotatably and removably carried by the support member.

Abstract: In the manufacture of plastic bags having interlocking profiled extrusions for the closure, the extruded plastic profiles are applied to a moving web of film immediately after extrusion of the profiles. The profiles are fused to the web on a first section of a fusing/cooling arcuate plate-like support member. Thereafter, the web is moved to a second cooled section of the arcuate plate-like support which is maintained at a temperature to allow the profiles to freeze to the web. The moving web of film is maintained under tension so that contraction of the film upon release compensates for the contraction of the locking profile as it cools to prevent puckering of the web. The locking profiles are applied to the web in an in-line process, which includes folding and heat sealing the moving web of film to form plastic bags.

The bevel angle is preferably one half of the pleat angle.

Abstract: Molten thermoplastic, such as polyethylene, and a hot melt adhesive are coextruded through a channel shaped profile die. While still molten, the channel shaped strip, having adhesive between the ribs thereof, is brought into contact with a moving web of a thermoplastic, e.g. polyethylene film, which is backed up by a roll at a controlled temperature. The temperature differential between the roll and the molten thermoplastic is maintained so that the thermoplastic adheres to the moving web upon contact and thereafter cools to set the thermoplastic in the channel shaped profile. The web is under tension so that contraction of the film upon release compensates for the contraction of the channel shaped strip as it cools.

Abstract: A moving, fibrous web is impregnated with a liquid by placing the liquid on the surface of the web, spreading the liquid over the web surface, pressuring a portion of the liquid into the web to partially saturate the web with the liquid and leave residual liquid on the web, and metering the residual liquid into a layer of substantially uniform thickness. This layer is then forced into the web to saturate it with liquid. This method is particularly effective for producing plastic pipe incorporating at least one layer of fibrous material saturated with liquid resin .Apparatus for practicing this method comprises a first surface transverse to the surface of the web, and a second surface converging with the web in the direction of travel of the web. The first surface performs the spreading step and the second surface performs the pressuring and metering steps.

Abstract: A simplified layup mandrel with no contour or twist is utilized by the method of this invention for forming the spar member of an aerodynamic rotor blade. A fiber glass tape is wrapped (laid-up) to a desired thickness onto the simplified mandrel to form a strap as the initial step. Because of the simple design of the mandrel, the laid-up strap when removed from the mandrel has a basic U-shaped configuration with straight extending legs having substantially parallel vertically oriented faces. This strap is then placed on a forming mandrel and contoured to the desired shape either by hand or by coining in a forming die. The contoured strap is then utilized in any of the various subassemblies or final assembly of the composite aerodynamic rotor blade.

Abstract: The overlapping edges of a continuously formed tubular configuration of plastic web are fused together between a backup ring and a sealing roller continuously heated by hot air directed against the periphery of the roller. When the heated roller is pressed in sealing engagement against the overlapped edges of the moving film it is rotated due to the frictional engagement of the roller with the film. A portion of the hot air impinges on blades extending laterally from opposite sides of the roller to apply torque thereto and thereby keep the roller spinning whenever the roller is out of frictional engagement with the overlapped edges of the continuously advancing web. By keeping the roller spinning it is evenly heated and hot spots are not allowed to develop as they would if the roller stopped while hot air continued to impinge on it. Cooling air is applied to the sealed overlapping edges after the sealing operation has been performed.

Advancing of the strip is accomplished on an intermittent basis between the horn and the anvil by means of the elements for continuously producing the tapes having a desired number of elements thereon.

Abstract: Three-ply web material is rolled approximately 360.degree. into the form of a cylinder within a preform cavity. A feed roller at the opening rotates continuously and a spring loaded pressure plate has an edge at the opening which forces the web material against the feed roller. After the trailing edge of the segment of web material has passed the edge of the pressure plate, contact between feed roller and web material is lost and the circumferential position of the seam of the preform is thus precisely located. There is a slight overlap between the ends of the material at the same. The preform is longitudinally transferred into a non-conducting cylindrical forming cavity where heat and pressure are applied to fuse the overlap and form the seam. Heat is applied by induction heating through the walls of the forming cavity to the aluminum ply at only the overlap area. Pressure is applied by an expandable balloon mandrel inside the preform.
