14 ABSTRACT In the process and apparatus for fully automatic laying and folding elongated textiles such as stockings, panty hose and the like, four folding conveyors withcirculating silicone coated belts are used. The textile is transported from a first folding conveyor to a second folding conveyor which have the same running direction. Once the textile reaches a predetermined position, a card laying arm takes a wrapping card from a wrapping card magazine and places the card onto the textile. The second folding conveyor and a third folding conveyor positioned in parallel thereto are raised by means of a hydraulic device. The textile and the wrapping card are pulled-in between the second and third folding conveyors which are now operated in their opposite running directions. The textile is delivered 1/3 folded onto a fourth folding conveyor which is equipped with eight circulating silicone transport belts. The remaining folding operations take place on the fourth folding conveyor and are performed by first, second and third folding rakes, the third rake being adjustable. The third rake can be reoriented by 180° to produce end folding in left hand or right hand direction. The positioning of the textile on the folding conveyors is controlled by means of photo-detectors. After folding is complete, the textile is transferred onto a transport conveyor which has a deceleration and acceleration function. The eight circulating, silicone coated belts of the transport conveyor deliver the folded textile to a packaging station at the transport speed thereof. Seven stripping fingers are associated with the transport conveyor which prevent the textile becoming entangled therein. The whole apparatus and process is electronically controlled and, thus, provides the advantage of higher efficiency and speed compared with conventional machines.
