ABSTRACT:
An apparatus for needling a fibrous web comprises a row of needle beams arrayed adjacently each other in a direction of an operating width. The needle beams may be attached to exchangeable needle boards and are driven with the needle boards up and down in a reciprocating motion path. The fibrous web is guided by a fibrous web support and a stripper positioned between the needle beams and the support. A conveyor conveys the exchangeable needle boards to and from the needle beams. The conveyor device extends alongside the row of needle beams and comprises revolving endless traction devices arranged at each side of the needle beams outside the reciprocating motion path, and needle board entrainment elements in the form of bearing flanges for supporting side edges of the needle boards. The bearing flanges are carried by the traction devices and are repositionable between a conveying position wherein they project into the reciprocating motion path and an inoperative position wherein they are outside the reciprocating motion path of the needle boards attached to the needle beams.
