Abstract
A semi-automatic loader for needle boards (2) includes a filling device (51) that presents felting needles (17) arranged at a ratio that is consistent with the ratio of holes of a needle board. A machine operator can then grasp the felting needles (17) by means of a multiple collet chuck (45) and set them in groups in the rows of holes of the needle board (2). This provides a loading method featuring extremely high productivity.

Method for setting felting needles (17) in the needle boards (2) of a felting machine, said needles having a working part (35) and a holding part (36), whereby said method comprises the following steps:
- providing a needle board (2) having a number of openings (3) that are designed to accommodate felting needles (17) and that are arranged at pre-specified distances;
- providing a multiple collet chuck (45) that is designed for picking up several felting needles (17) in that said collet chuck grasps the holding part (36) of said needles;
- inserting a group of felting needles (17) in the multiple collet chuck (45), said needles being aligned parallel in longitudinal direction;
- inserting at least one of the working parts (35) of the felting needles (17) held by the multiple collet chuck (45) in the openings (3) of the needle board (2);
- and
- pushing of the holding parts (36) of the felting needles (17) into the openings (3) of the needle board (2).
Device for setting felting needles (17) in a needle board (2) of a felting machine, said needles having a working part (36) and a holding part (36), whereby said device comprises the following components:
- a holding device (4) for a needle board (2) that is to be loaded in order to hold the needle board (2) in a planting position;
- a multiple collet chuck (45) that is disposed to grasp and release, in a controlled manner, a group of felting needles (17) that are aligned parallel to each other;
- a filling device (51) for loading the multiple collet chuck (45) with several felting needles (17);
- and
- a depressing device (27, 28) for pushing the holding parts (36) of the felting needles (17) planted in the openings (3) into said openings (3) of the needle board (2).
