Abstract
A fabric expander apparatus for tubular fabrics includes at least two first internal wheel and belt assembly groups kept in position inside and on the sides of the fabric tube by second external corresponding wheel and belt assembly groups. Each first internal wheel and belt assembly group includes a plate which has a wheel conducted by counter-wheels of the second external group and driven wheels. All these wheels from the first internal wheel and belt assembly group have a part of the perimeter exposed outside the plate and in a direction of the second external group, to receive a conveyor belt, which moves in a desired direction to transport the fabric tube. Motor wheels of the second external group are pressed against the conveyor belt and against the wheels of the first internal wheel and belt assembly group to compress the fabric and to contribute to transport it in the desired direction.
