ABSTRACT:
Device for individually holding textile articles, comprising a structure supporting a plurality of holding elements 6 shaped like coils or plates disposed side-by-side and axially movable, and piston operated levers for moving the holding elements away from and close to each other as they come in contact with the fabric of the article to be picked up.
The holding elements may advantageously consist of coils of a tensile spring shaped as a cylindrical helix which is suitably extended, before coming in contact with the fabric, by the piston operated levers, and then is released for resilient contraction movement upon its contact with the fabric.
Advantageously, the device comprises controls of the correct holding of the article, thereby allowing the automation of the device for the use thereof in the handling of textile materials.
