A double-layer longitudinal wrapping mold is disclosed, including a base, a first longitudinal wrapping structure, a first pressing structure, a second longitudinal wrapping structure, a second pressing structure and a first necking structure. The first longitudinal wrapping structure is disposed on the base and has a first guide hole, a first outer layer wrapping hole and an inner layer wrapping hole. The first pressing structure is disposed on the base and has a first pressing hole and a second outer layer wrapping tape hole. The second longitudinal wrapping structure is disposed on the base and has a second guide hole and a third outer layer wrapping tape hole. The second pressing structure is disposed on the base and has a second pressing hole and a fourth outer layer wrapping tape hole. The first necking structure is disposed on the base and has a necking hole.

Provided are a flexible tube for an endoscope, the flexible tube having a flexible-tube base containing metal as a constituent material, a cover layer covering an outer periphery of the flexible-tube base, and a primer layer disposed between the flexible-tube base and the cover layer and including at least one of a specific silane coupling agent, an aluminum alkoxide compound, a zirconium alkoxide compound, or a titanium alkoxide compound, in which the cover layer includes, at least on a side in contact with the primer layer, a polyester having a naphthalene structure, an endoscopic medical device using the flexible tube, a method for producing the flexible tube for an endoscope, and a method for producing the endoscopic medical device.

A passivating flexible insulation blanket positionable about a pipe includes an insulation core, an enclosing fabric, and a non-consumable passivator. The insulation core is substantially hydrophobic and includes a microporous material. The enclosing fabric fully encapsulates the insulation core to form a capsule or pouch about the insulation core. The non-consumable passivator is non-consumable such that there is no appreciable change to a mass of the non-consumable passivator after an extended time of activation. The non-consumable passivator is deposited into the insulation core and has a composition soluble in water. The non-consumable passivator includes a leachable component that leaches from the insulation core and is capable of neutralizing acidic components. The leachable component is water soluble and is capable of reacting with a surface of the pipe to form a protective coating on the pipe to aid in inhibiting corrosion formation on the surface of the pipe.

This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with a reinforcing stiffener. The corrugated pipe may include an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. In some embodiments, a stiffener may be positioned within the corrugation valleys. In other embodiments, a stiffener may be positioned within the corrugation crests.

A sensing apparatus includes a sheath, a central member disposed in the sheath, at least one optical fiber disposed with the central member, and a film adhesive disposed between the central member and the sheath, the film adhesive provided in one or more sheets or strips and disposed in one or more layers between the central member and the sheath, and the film adhesive attached to the sheath.

The present disclosure relates to the field of apparatuses for manufacturing a display. It discloses an apparatus for sticking cloth, including: a rack; a workbench arranged on the rack; a roller frame arranged above the workbench and provided with a pair of clamps which are configured to clamp a rubbing roller onto which a cloth will be stuck; a horizontal moving mechanism mounted on the rack and configured to drive the roller frame to move horizontally; and a heating pad mounted on the workbench and configured to heat a rubbing cloth and a double sided adhesive tape. By means of heating the rubbing cloth and the double sided adhesive tape by the heating pad, the air bubbles on the surface of the rubbing roller may be reduced to optimize the rubbing alignment process. The present disclosure also provides a method for sticking cloth.

The present disclosure provides various aspects for mobile and automated processing utilizing additive manufacturing and the methods for their utilization and for making material dispensing element arrays for use of the additive manufacturing device.

The invention refers to a method for laminating a tubular film (1) preferably manufactured by means of blown film (co-) extrusion with a material capable of absorbing resin or liquids, wherein the tubular film (1) is laminated over its entire perimeter with several layers (10, 11, 12, 13; 20, 21, 22; 30, 31) overlapping or positioned directly opposite one another on their front sides containing material capable of absorbing resin or liquids, so that essentially there are no areas left along the perimeter of the tubular film (1) not covered by the laminated layers (10, 11, 12, 13; 20, 21, 22; 30, 31). The invention also refers to a tubular film laminated in such a way and to various applications.
