An apparatus for shearing, tigering, napping or other surface treatment of a finite length of a textile fabric, particularly pile and plush fabrics, is disclosed which is especially adapted for experimental research and development usage in a laboratory setting. The apparatus includes a rotatably driven roller having a fabric surface-engaging periphery and an arm assembly for supporting the fabric piece for presentation to the roller, the arm assembly being movable between a fabric-loading position spaced from the roller and a treatment position in close adjacency to the roller. The arm assembly has a pair of fabric clamps mounted to respective chain assemblies which can be moved in opposite or the same directions independently or in tandem to facilitate attachment of the opposite ends of the fabric to the respective clamps by movement of the clamps toward one another, fabric tensioning by movement of the clamps away from one another, and fabric travel past the roller by coordinated unitary movement of the clamps in tandem. Guide rollers within the apparatus alternatively enable either a continuous loop of fabric or an indeterminate traveling length of fabric to be processed.
