摘要:
A self-contained, portable and automated apparatus and method for wrapping edges of a panel with a protective and/or decorative laminate material comprises conveying means for moving the panel from an entry end of the apparatus to an exit end of the apparatus, lifting means for transversely deflecting the flap upward to a position substantially perpendicular to the front surface of the panel as the panel is conveyed, adhesive application means for applying an adhesive to a back surface of the panel proximate the edge substantially throughout the length of the panel as the panel is moved past the adhesive application means, a folding bar positioned downstream from the adhesive application means at an angle of about 135 to 170 degrees relative to a trailing part of the edge to transversely deflect the flap downward toward the adhesive on the back surface of the panel, and a roller positioned downstream from the folding bar and arranged to spin inwardly over the flap at an angle of about 130 to 150 degrees relative to the trailing part of the edge to cause the flap to stretch inwardly and be secured to the back surface of the panel.

摘要:
A fabrication method of forming a thermoplastic composite laminate material with tailored and varying thickness in a continuous process. This process utilizes automated equipment or hand lay-up to collate parts or components into a multi-layer stack. Each stack contains all plies, including ply build-up areas, tacked in the proper location to maintain orientation and location. The consolidation tooling contains all necessary part features and is coordinated to the customized multiple ply stacks to form a single integrated thermoplastic composite laminate potentially having areas of differing thickness from these multiple ply stacks.
摘要:
A process for the reduction of the residual monomer content and enhancement of the wet strength of articles formed from water absorbent crosslinked polymer foams containing units derived from monoethylenically unsaturated acids, which comprises treating the formed articles with at least 0.5% by weight of a polymer containing primary and/or secondary amino groups and having a molar mass of at least 300, the formed foam articles thus obtainable and use of the wet strength enhanced formed foam articles in hygiene articles.
摘要:
A method for making an elastic composite for incorporation into an absorbent garment. An elastic applicator (1007) is configured to move a section of a continuous strand of elastic (WW) about a plane. A web of material is conveyed in a web moving direction such that the web intersects the plane. T applicator moves the elastic element about the plane to apply the elastic onto the web along a direction transverse to the web moving direction such that the web draws the elastic from the applicator as the web is conveyed away from the plane. The applicator may be a spin cylinder or bracket operated to spin the elastic about the moving web to apply elastic to the web.

The present invention relates to a process for manufacturing composite ring frames for aeronautical fuselages by means of the application of the RTM technology to two preforms with C- and L-shaped sections manufactured using two tools (21, 55) in the following steps: providing the material; hot-forming planar rectangular laminates (41); hot-forming laminates of right angle section (51) on one part of right angle section of the first tool (21), placing an elastic membrane (55) and applying a temperature and vacuum cycle; hot-forming the preforms into a C shape (11) and L shape (13) on a second curved tool (55) by deforming said laminates of right angle section (51) thereon, and applying a temperature and vacuum cycle. The invention also relates to said tools (21, 55)
