Abstract: A sewing machine operating station which cooperates with an overhead conveyor system having a number of trolleys which convey partly-formed garments between working stations, each trolley having a delivery arm from which garments can be suspended, and delivered to a working station. Each working station comprises a table, a sewing machine mounted on the table, and a working surface adjacent to the sewing machine and onto which a partly-formed garment can be placed in order to undergo a sewing operation. An inverted L-shaped guide is mounted on the table and can be coupled-up with the delivery arm of a trolley so as to guide a supply of partly-formed garments, suspended therefrom, to a position adjacent to the working surface.
