Abstract

Systems and methods for backing material for pretensioned tufted products. The system may include at least first and second tensioning assemblies and a guide assembly. Each tensioning assembly may have a backing supply subassembly for supporting the backing material and a roller assembly for effecting movement of the backing material under the desired tension. The roller assembly may include a drive roller for pulling the backing material from the backing supply sub-assembly, and a compensator for receiving the backing material from the drive roller. The guide assembly may simultaneously receive the tensioned backing material from the tensioning assembly and position the backing materials in contact with each other for delivery to the tufting machine at the desired tension.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 442,711 filed January 5, 2017. The disclosures of the applications cited above are incorporated herein by reference in their entirety. technical field [0003] The disclosed invention relates to systems and methods for pretensioning backing materials for tufted products. Background technique [0004] During the manufacture of tufted products such as carpets or tufts, a roll of primary backing material may be supplied from a supply roll and continuously fed through a tufting machine. The tufting machine may be provided with a reciprocating needle bar having a series of spaced apart tufting needles arranged on the tufting machine for inserting the tufts into the backing material. Due to the inherent stretchability of the backing material, the tension in the backing material naturally varies during operation of the tufting machine based on the weight ...
