Abstract
The guidance system pulls sheet material along its length from a supply and moves the sheet material across a work table through a sewing machine and the like. The sheet material extends through a loop and is moved from a level displaced from the level of the work surface of the work table about a horizontal guide bar and then onto the work table. An edge detector senses the edge of the sheet material, and the guide bar is pivoted about an upwardly extending axis in response to the drifting of the edge of the sheet material away from the desired predetermined path of movement toward the sewing machine to guide the edge of the material back to its desired path. The edge portion of the sheet material is carried by bands and tapes movable along the work surface of the work table, up an incline to the bed of the sewing machine, and the edge of the sheet material is folded as it moves up the incline to the sewing machine needle, and the folded and sewn hem of the sheet material leaving the needle of the sewing machine is pulled at a faster rate than the main body of the sheet material along the work table.
