Definitions

• the present invention relates to a universal device for removing an article of footwear from a solid metal shape or from a tube or from two shapes arranged side by side, the articles being socks or pairs of socks with small or very long uppers, pantyhose legs or tights assembled, or lady's stockings knitted with all kinds of fibers. All these articles being on forms of different heights with normal inclination of the foot making an angle of about 40 ° with the vertical and having a normal heel.
• the first is made up of two pliers covered with rubber, which grip the article at the top of the form and tear off the latter by pulling strongly on it, so as to remove it from the form.
• This device is currently used on 95% of the sock forming machines on the market. It is then necessary to tilt the article, which is held at its top by the clamps and which hangs vertically from top to bottom, from the vertical position to the horizontal position, by means of a racket animated by a very rapid circular movement .
• the second type of puller consists essentially of two belts, which after having pinched the article on the form, are put in rotation to extract it from the latter. It has the advantage of being able to quickly scroll through very long articles, and by ' a judicious arrangement of the belts to gently move the article from the vertical position to the horizontal position. It is generally used to scroll through large articles.
• sliders are used on forming machines, either specialized in the treatment of socks, or in the treatment of tights with heights of different shapes and, also, very different inclinations of feet.
• the aim of the present invention is to eliminate all these drawbacks by making it possible to scroll with the same device, all kinds of footwear, from small short-sock socks, to very large tights, including children's tights, men's socks, and ladies' stockings, and this in all kinds of materials, with a normal inclination of the foot, that is to say to be universal.
• the present invention is characterized by the fact that the foot of the article is taken in tweezers by two very short conveyor belts, arranged vertically and, then this assembly is driven in a translational movement in the same direction as the axis of the foot of the form, this to extract only the foot of the article, the two conveyor belts remaining fixed in rotation.
• a pair of fingers located on 'both sides of the form which come in a horizontal rotational movement enter the "bottom of the article, and are then driven by a rising movement in the same speed as the speed of movement of the assembly of the two conveyor belts.
• the two conveyor belts come to rest tangentially to a mat located horizontally, while the two ascent fingers of the article stop simultaneously It is characterized by the fact that, in a second step, the complete extraction of the article is carried out by the rotation of the different conveyor belts arranged judiciously so that the article ends its journey on an inclined conveyor belt. at 45 °, always helped in this by the two lifting fingers of the article which accompany it at the same speed as the linear speed of the conveyor belts era that the article thus paraded is not stretched or wrinkled during the last stage of parade by the various carpets.
