Device for the mechanical insertion of cursors onto open slide fasteners, already applied on garments

Device for mechanical insertion of a cursor onto a slide fastener composed of two belts carrying teeth already applied to garments, comprising a carrying structure to be applied on a table consisting of front and rear parallel vertical plates, said front plate having an extension which carries an opening therein, a block cursor support applied on said front plate of said structure in correspondence with the opening of the extension to receive and support the cursor to be inserted, a first fluid pressure cylinder positioned on said extension, a pressing element controlled by said fluid pressure cylinder so that the driving of the cylinder determines the locking of the cursor in its support, a pair of parallel grippers having upper and lower jaws placed on both sides of the cursor support to grasp the ends of the two belts of the fastener to draw them backwards and to engage the two series of teeth in the cursor, longitudinal guides extending between said two vertical plates of the structure, a slide plate carried by said guides, the lower jaws of said grippers being carried by said slide plate and a second fluid pressure cylinder having a shaft positioned on said front plate to operate said grippers.
