Abstract

This relates to the manufacturing of reinforced materials, such as reinforced cellular materials or reinforced textiles, for example. Reinforcement is achieved by including a textile semi-finished product into the material to be reinforced, by providing the semi-finished product at the rear side of the material in a zigzag or wave-like manner and then pulling the semi-finished product through the material by a plurality of needles. Thus, the manufacturing process may be performed in a time saving manner.

First claim

What is claimed is:

1. Method for producing reinforced cellular materials, reinforced textiles, and combinations thereof, the method comprising:
guiding a plurality of needles through a material to be reinforced, such that individual needles of the plurality of needles penetrate a rear surface of the material;
feeding, in a linear manner, a semi-finished textiles product on a side of the rear surface of the material;
arranging the semi-finished textiles product in a non-linear manner on the side of the rear surface of the material to be reinforced by means of a subsequent displacement thereof after the semi-finished textiles product has been fed on the side of the rear surface of the material in the linear manner;
inserting the semi-finished textiles product into the individual needles; and
withdrawing the plurality of needles from the material, to draw a respective portion of the semi-finished textiles product by each one of the individual needles into the material in each case.

2. Method according to claim 1 , further comprising:
feeding, in a linear manner, a second portion of the semi-finished textiles product on the side of the rear surface of the material;
wherein the semi-finished textiles product is arranged in a non-linear manner by means of a subsequent displacement thereof.

3. Method according to claim 1 , wherein the semi-finished textiles product is arranged in a non-linear manner by means of the engagement of at least one of a plurality of hooks, rollers, and pegs into the semi-finished textiles product and of the subsequent displacement of the hooks, rollers or pegs in a plane which is substantially parallel to the plane of the rear surface of the material.

4. Method according to claim 3 , wherein the hooks, rollers, and pegs are displaced in a sequence, such that at any point in time just one individual hook, one individual roller or one individual peg, or a sub-group of hooks, rollers or pegs, is moved.

5. Method according to claim 1 , further comprising:
carrying out an intermediate stroke of the plurality of needles, such that the semi-finished textiles product is taken up by the individual needles.

6. Method according to claim 1 , further comprising:
fixing the semi-finished textiles product to the rear surface of the material.

7. Method according to claim 3 , further comprising the step of:
severing the semi-finished textiles product in the region of the hooks, rollers or pegs.

8. Method according to claim 3 , further comprising the step of:
forming a seam by arranging a loop of the semi-finished textiles product on a front surface of the material, through which loop a further loop of the semi-finished textiles product is then drawn;
wherein the loops are arranged in a direction which has an angle that does not equal 0 degree with respect to a direction along which the semi-finished textiles product is arranged on the side of the rear surface of the material after it is drawn into the material.

9. Multi-needle machine for producing reinforced cellular materials, reinforced textiles or combinations thereof, comprising:
a plurality of needles which are movable in a stroke-like manner for piercing a material to be reinforced, for taking up a semi-finished textiles product and for drawing a respective portion of the semi-finished textiles product by each one of the plurality of needles into the material; and
a feed device for the linear arrangement of the semi-finished textiles product on a side of the rear surface of the material to be reinforced;
wherein the feed device is configured for a subsequent displacement of the linear arrangement of the semi-finished textiles product such that a non-linear arrangement of the semi-finished textiles product on the side of the rear surface of the material to be reinforced is provided after the semi-finished textiles product has been fed on the side of the rear surface of the material in the linear manner.

10. Multi-needle machine according to claim 9 , further comprising:
a needle beam carrying the plurality of needles.

11. Multi-needle machine according to claim 9 , wherein the feed device comprises a plurality of hooks, rollers or pegs for the non-linear arrangement of the semi-finished textiles product on the side of the rear surface of the material.

12. Method for producing reinforced cellular materials, reinforced textiles or combinations thereof, said method comprising the steps of:
guiding a plurality of needles through a material to be reinforced, such that individual needles of the plurality of needles penetrate a rear surface of the material;
arranging a semi-finished textiles product in a non-linear manner on a side of the rear surface of the material to be reinforced;
inserting the semi-finished textiles product into the individual needles;
withdrawing the plurality of needles from the material, thereby drawing a respective portion of the semi-finished textiles product by each one of the needles into the material in each case;
feeding, in a linear manner, a first portion of the semi-finished textiles product on the side of the rear surface of the material; and
feeding, in a linear manner, a second portion of the semi-finished textiles product on the side of the rear surface of the material;
wherein the semi-finished textiles product is arranged in a non-linear manner by means of a subsequent displacement thereof.

13. Method according to 1 ,
wherein the semi-finished textiles product is arranged in a non-linear manner by means of the engagement at least one of a plurality of hooks, rollers and pegs into the semi-finished textiles product and of the subsequent displacement of the hooks, rollers and pegs in a plane which is substantially parallel to the plane of the rear surface of the material;
wherein the hooks, rollers or pegs are displaced in a sequence, such that at any point in time just one individual hook, one individual roller or one individual peg, or a sub-group of hooks, rollers or pegs, is moved.
