ABSTRACT:
An apparatus for conveying an article, as during a sewing operation, includes a pair of driving pulleys supported on a first support simultaneously rotatably by an electric motor and spaced apart from each other transversely of the apparatus and a pair of driven pulleys supported simultaneously rotatably on a second support and spaced apart from each other transversely of the apparatus. A pair of first fixed intermediate pulleys and a pair of first movable intermediate pulleys are supported simultaneously rotatably on the first support below the driving pulleys and between the driving pulleys and the fixed intermediate pulleys, respectively. The second support is spaced apart from the first support longitudinally of the apparatus and the first and second supports are horizontally movable to and away from each other. A pair of second fixed intermediate pulleys and a pair of second movable intermediate pulleys are supported simultaneously rotatably on the second support below the driven pulleys and between the driven pulleys and the second fixed intermediate pulleys. The first and second movable intermediate pulleys are horizontally movable to and away from each other. The two pulleys of which each pair of intermediate pulleys consists are spaced apart from each other transversely of the apparatus. A pair of endless conveyor belts are spaced apart from each other transversely of the apparatus and are each wound around one of the driving pulleys, one of the driven pulleys and one pulley of each pair of intermediate pulleys. Each belt has an effective conveyor portion travelling horizontally from one of the driven pulleys to one of the driving pulleys upon rotation of the motor.
