The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. A first beam is rotated to unwind a first plurality of elastic strands from the first beam in the machine direction. The first plurality of elastic strands are positioned between the first substrate and the second substrate to form the elastomeric laminate. Before the first plurality of elastic strands are completely unwound from the first beam, a second beam is rotated to unwind the second plurality of elastic strands from the second beam. Subsequently, the advancement of the first plurality of elastic strands from the first beam is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first beam to a subsequently utilized elastic material drawn from the second beam.

The present disclosure relates to absorbent article's chassis that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics. The elastics in the chassis may be oriented parallel or transverse to the longitudinal axis.

The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. First spools are rotated to unwind first elastic strands from a first unwinder in a machine direction. The first elastic strands are positioned between the first substrate and the second substrate to form an elastomeric laminate. Before the first elastic strands are completely unwound from the rotating first spools, second spools are rotated to unwind second elastic strands from a second unwinder. Subsequently, the advancement of the first elastic strands from the first unwinder is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first spools to a subsequently utilized elastic material drawn from the second spools.

Systems and methods are provided for septa for acoustic cells. One embodiment is a method that includes fabricating a septum of a cell of an acoustic panel, by heating a material into a molten material, depositing the molten material to form a lower chamber of the septum that extends vertically upwards and includes an entry, iteratively depositing layers of the molten material, each layer comprising a filament at the entry that includes overhangs with respect to vertically adjacent layers, and forming openings at locations of the overhangs.

A thermal welding marking system for attachment to a thermal welding machine including: a hammer arm rotatably connected to a mounting bracket attached to the thermal welding machine, wherein a distal end of the hammer arm is shaped to receive a marker or pen therein; a cable or spring connected to the distal end of the hammer arm; a cable connecting the hammer arm to a hand lever mounted adjacent to hand controls on the thermal welding machine, wherein movement of the hand lever raises or lowers the distal end of the hammer arm and thereby raises or lowers the marker or pen therein. In operation, the thermal welding machine is advanced across the edges of overlapping building roofing material and the marker or pen is intermittently lowered/raised to mark locations along a seam of the edges of overlapping building roofing material where the seam is either open or closed.

A manufacturing process is provided during which a thrust reverser cascade is formed for an aircraft propulsion system. During the formation of the thrust reverser cascade, a first panel of material is stamped into a first corrugated body. A second panel of material is stamped into a second corrugated body. The first corrugated body is bonded to the second corrugated body.

A mechanically lined pipe including a host pipe having an inner surface which is lined with a metallic liner, the metallic liner having an inner surface which is lined with a polymer liner which presses the metallic liner against the inner surface of the host pipe, as well as to methods of reeling and unreeling the mechanically lined pipe. A method of making a mechanically lined pipe having an internal polymer liner, the mechanically lined pipe including a host pipe having an inner surface which is lined with a metallic liner, the method including the steps of: (a) providing a mechanically lined pipe having an internal diameter, (b) providing a polymer liner having an outer diameter which is greater than the internal diameter of the mechanically liner pipe, (c) reducing the outer diameter of the polymer liner such that it is less than the internal diameter of the mechanically liner pipe, (d) inserting the polymer liner into the mechanically lined pipe, and (e) allowing the polymer liner to expand such that it presses the metallic liner against the inner surface of the host pipe.

A trim component for an interior of a motor vehicle has a film and has a carrier from a thermoplastic plastics material. The film has a relief structure, the carrier has a lattice structure having lattice members, and the carrier is back-molded on a rear side of the film such that the lattice members are connected in a materially integral manner to the rear side of the film.

A method for producing filled containers (16) from preforms (13). Each of the preforms is transferred to a circulating molding and filling element (14) of a molding and filling station and is shaped into the respective container in a subsequent molding and filling process in a mold under the effect of pressure from a supplied filler, wherein the mold is designed in multiple parts, including a base mold (21) and mold sides (19, 20), and each container is clamped between the base mold at the bottom and the molding and filling element at the top at least at the end of the molding and filling process. The container is separated from the respective molding and filling element and the respective mold after the molding and filling process. The mold sides are removed from each container before the molding and filling element and the base mold are separated from the container.

A method of forming a container (1) and a container (1) formed thereby. A preform (2), having a generally cylindrical body (60, 8) extending between a closed end (12) and an open mouth, is placed within a mold (20, 22) having surfaces corresponding in shape to the desired container (1). An incompressible medium, which is the end product that remains in the molded container (1), is injected under pressure into the preform (2). Under the influence of the incompressible medium, the preform (2) is expanded into contact with the surfaces defining the cavity, simultaneously forming and filling the container (1). During expanding of the preform (2), portions of the plastic material are forced into a series of recesses (72) defined in the cavity surface (82, 85). With the incompressible medium contained therein, the container (1) is removed from the mold (20, 22) and including a series of raised dots corresponding to the series of recesses (72) defined in the cavity surface (82, 85).
