ABSTRACT:
In a needle loom for needling a fiber batt continuously moved through the needle loom, a horizontal driving apparatus connected to a needle bar for horizontally driving said needle bar to and fro is provided which is driven in synchronism with a vertical driving apparatus providing the needle bar with a reciprocating up and down movement by which needles affixed to the needle bar are stitched into the fiber batt to be needled. The timing of the horizontal and vertical movements imposed onto the needle bar is adjusted in a manner that the needle bar horizontally follows the movement of the fiber batt when the needles are stitched in the fiber batt, whereas in the horizontal return stroke of the needle bar its needles are out of the fiber batt. In a double needle loom in which needles are disposed at two needle bars provided on either side of the fiber batt so that needles are stitched into the fiber batt on either side thereof, each needle bar is provided with its own horizontal drive, elements are provided for preventing a collision of needles when stitched into the fiber batt.
