The present disclosure relates to apparatuses and methods for making patterned apertured substrates that may be used as components of absorbent articles. During the manufacturing processes, a precursor substrate advances in a machine direction between a pattern roll and an anvil roll. The pattern roll rotates about an axis of rotation and includes a plurality of pattern surfaces, wherein the substrate is compressed between the anvil roll and the pattern surfaces of the pattern roll to form discrete bond regions in the substrate. The pattern surfaces on the pattern roll are formed on continuous threads extending circumferentially around the axis of rotation along helical paths parallel with each other. As such, the pattern surfaces press the substrate against the outer circumferential surface of the anvil roll in the different axial locations along the cross direction as the pattern roll rotates when forming the discrete bond regions.

A compression collar is used for reinforcing an interference fit between a piping end and a fitting. The compression collar comprises a reinforcing ring having a tubular geometry with a radially-inward facing surface and a radially-outward facing surface. A sleeve is received around, at least in part, a portion of the radially-outward facing surface of the reinforcing ring and this sleeve wraps around one axial end of the reinforcing ring to form a stop edge thereon.

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 method for manufacturing tanks for storing or containing a fluid under pressure and a method for manufacturing pipes for containing or channeling a fluid under pressure, such as for storing, containing or channeling hydrogen, natural gas or a hydraulic fluid. The method is less complex than known procedures, can be employed in a continuous or semi-continuous manner and allows for a lower thickness of the shell made from the fibres. The method comprising providing a liner having a cylindrical portion with two ends and two dome portions at the respective ends of the cylindrical portions or a liner having a cylindrical portion and one or two open ends; fabricating a tube of fibre filaments by means of the pullwinding method; and wrapping the tube of fibre filaments onto the liner such that at least the cylindrical portion of the liner is enclosed by the tube of fibre filaments.

A method for sealing a telecommunications product is disclosed. The method includes securing a telecommunications product to an apparatus having heat blasters, and initiating a heat sealing operation that includes moving the heat blasters along a first plane toward a shrink wrap tubing until the heat blasters surround the shrink wrap tubing; delivering hot air from each heat blaster; and moving the heat blasters along a second plane along a predetermined length of the shrink wrap tubing, the second plane being orthogonal to the first plane.
