Abstract
Two laps are needled together between longitudinal guide tubes which maintain spacing between the laps and downstream of the needling position, the tubes release an interleaving material between the laps and between the rows of bridges formed by needling, the interleaving material consisting of resin, powder, fibers, tubes, wires, threads, and/or electrical conductors.
Claims26
A device for manufacturing a composite lap, comprising means (2), (4) for advancing and guiding two basic laps (A) parallel to each other, mechanical means (22) for determining a space between said laps, means (10), (12), (18) for joining the two laps together along longitudinal join lines (14) at a position where said mechanical means are effective for mechanically spacing said laps apart from each other, and means (19), (26) for guiding an interleaved material (B), (C) between the two laps while said laps are advanced parallel to each other, to introduce said interleaved material into the longitudinal spaces defined by the mechanical means between the longitudinal join lines (14).
A method for producing a composite lap comprising
- driving and guiding two basic laps (A) in a substantially parallel relationship through a joining position and through a subsequent interleaving position;
- joining said two basic laps (A) to each other at the joining position along longitudinal join lines (14) while maintaining, at said joining position, a predetermined distance between said laps by means of a mechanical action between the join lines which are being created to produce between the laps, as said join lines, rows of join bridges with each join bridge having a preset length;
- guiding at least one interleaved material (B, C) between the laps (A) as both laps are being joined to introduce said interleaved material at the interleaving position into the longitudinal spaces produced between the longitudinal join lines by said mechanical action.
A method for producing a composite lap comprising:
- feeding two basic laps on either side of a table having longitudinal ribs;
- driving and guiding said two basic laps (A) in a substantially parallel relationship through a joining position and through a subsequent interleaving position;
- at the joining position, joining said two basic laps (A) to each other between the ribs thereby to form longitudinal join lines (14) while said ribs maintain, at said joining position, a predetermined distance between said laps, thereby to produce between the laps, as said join lines, rows of join bridges with each join bridge having a preset length;
- feeding at least one interleaved material into longitudinal ducts (26) located within the ribs so that the interleaved material, on leaving the ribs (22) at a downstream end thereof corresponding to the interleaving position, settles in the longitudinal spaces produced between the basic laps (A) and between the join lines (14).
A method for producing a composite lap comprising:
- driving and guiding two basic laps (A) in a substantially parallel relationship through a joining position and through a subsequent interleaving position;
- joining said two basic laps (A) to each other at the joining position along longitudinal join lines (14) while maintaining, at said joining position, a predetermined distance between said laps by means of a mechanical action between the join lines which are being created to produce between the laps, as said join lines, rows of join bridges with each join bridge having a preset length;
- guiding between the laps (A), as both laps are being joined, at least one interleaved material (B,C) comprising a thermoformable resin, to introduce said interleaved material at the interleaving position into the longitudinal spaces produced between the longitudinal join lines by said mechanical action.
