Abstract
Abstract In order to individually pick up and temporarily hold hosiery permeable articles, especially tubular articles like panty-hoses and stockings, and instantaneously stretch apart their elastic edges their automatic transfer, a holding device with adhesive and an air jet is utilized. The device includes a tape motorized to advance with intermittence between two elements provided for driving and tensioning the tape, and with a block for the support of the holding zone of the tape and an underlying support for more articles in overlapping relationship to form a stack. Nozzles for supplying jets for compressed air are located adjacent and perpendicularly oriented to the holding zone of the article, and in such a way as to act in a direction opposite to that of the retention force of the adhesive tape, thereby to pass through the article stretching out the elastic edge of the article as soon as this has moved away from the relevant support.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
330 words
Device for the temporary holding of articles of hosiery fabrics with permeable surfaces, especially tubular pantyhoses and stockings, comprising: a holding device with adhesive, including a tape-like adhesive element having a holding zone, two transmission and tension members, drive means for intermittently moving the adhesive elements forwards between the two transmission and tension members, a block for the support of the holding zone of the adhesive element and an underlying support for a plurality of the articles each equally oriented and overlapping to form a stack; means for providing at least a jet of compressed air acting in the vicinity of at least one of the edges of said holding zone of the tape, at an inclined direction with respect to the permeable holding surface of the articles and in an opposite direction with respect to that of the retention force of the adhesive tape, said means for providing at least a jet of compressed air including at least a body fixed to the support structure of the holding device with adhesive between the two transmission and tension elements of the tape, laterally to the holding zone of the tape, said body being provided with a plurality of nozzles communicating through a common duct with a supply of compressed air, the flow of compressed air being activated and respectively cut off, by means of a solenoid valve inserted on the supply duct and associated to a timer and whose intervention is synchronized with the holding device and the articles support, the jet of compressed air being generated after the holding of each one of the articles of the stack by the adhesive zone of the holding device and during at least a fraction of the phase for the withdrawal of the support with the articles from the holding device with adhesive so that the jet of compressed air passes through the permeable holding surface urging a next adjacent underlying article surface away from the holding surface thereby separating the surfaces.
