Abstract
The description relates to a facility for needling of fleece with at least one needle board (2) that can be driven to and fro in stitching direction (4) by means of pushing rods (3) borne displaceable in one guide sleeve (10) each, and with an additional drive (11) reciprocating in fleece feed direction (9) and effective on the movably borne guide sleeves (10), which is equipped with two parallel eccentric shafts (12, 13). To achieve simple constructional features it is suggested to bear the guide sleeves (10) via two brackets (16, 17) on the eccentrics (18) of the two equidirectionally driven eccentric shafts (12, 13), and to connect them non-rotatable with at least one of these brackets (16, 17).
Claims2
An apparatus for needling a fleece fed to the apparatus in a feeding direction, which comprises
- (a) at least one needle board,
- (b) pushing rods for driving the needle board to an fro in a stitching direction,
- (1) each pushing rod being displaceably borne in a guide sleeve, and
- (c) an additional drive engaging each guide sleeve for reciprocating the guide sleeve in the feeding direction of the fleece, the additional drive comprising
- (1) two equidirectionally driven, parallel eccentric shafts, and
- (2) two brackets carrying the guide sleeve on the two eccentric shafts, the guide sleeve being nonrotatably connected to at least one of the brackets.
