Abstract
Apparatus for feeding a fiber batt to a needle loom, in which a gusset gap is filled between the reversing roller of an upper pre-compression conveyor band and an upper supply roller by means of a slim transmission roller, which is suspended at its length at several locations, in order to avoid sagging. The suspensions can consist of ribbons, which carry the transmission roller, or they can be formed by holding fingers which are integrally formed with guide fingers of a finger roller and which are located in respective circumferential grooves in the transmission roller. In an alternative the transmission roller is divided into several segments and roller bearings are provided at the connection positions of the segments and are suspended from above (FIG. 1).
Claims20
Apparatus for feeding a fiber batt in a transport direction to a needle loom, comprising a pre-compression means including an outlet end and a batt support means, an endless continuously rotating pre-compression conveyor band arranged above the batt support means, a reversing roller for moving the conveyor band in the transport direction of the fiber batt at the outlet end of the precompression means, a lower supply roller and an upper supply roller mounted above the lower supply roller, said supply rollers forming a nip and being located between the pre-compression means and an intake of a needle loom, with the upper supply roller being proximal to said reversing roller, so that a gusset gap of approximately triangular cross-section is formed between the pre-compression band guided around the reversing roller and the upper supply roller, a transmission roller of low surface friction in said gusset gap, the circumference of said transmission roller being proximal to the surfaces of the pre-compression conveyor band and the upper supply roller, a plurality of bearing means distributed along said transmission roller to suspend said transmission roller to avoid sagging thereof, and means for driving said transmission roller in a direction in which the upper reversing roller and the upper supply roller are driven.
