Abstract
The invention relates to a device for taking up and displacing knitted or woven articles which are disposed in a pile, both when folded and not folded. The device is a combination of a first needle type gripping means with a vacuum gripping means and a supplying means. The needle type gripping means raises an edge of an article in the pile and, during a relative movement occurring between the vacuum gripping means and the supplying means, the latter progressively conveys this article towards the vacuum gripping means until said article adheres thereto as a result of a vacuum effect.
Claims11
A device for gripping one by one from a pile and for displacing knitted or woven articles, including a vacuum gripping means and a needle type gripping means acting together functionally together, wherein said two means are combined with a third, supplying means, the vacuum gripping means having an adherence surface with a first extremity and a second, opposite, extremity, said adherence surface having at least the same area as the said articles, the needle gripping means being placed in the vicinity of the first extremity of the vacuum gripping means so that the vacuum and needle gripping means may be displaced together as they grip one of said knitted or woven articles and the supplying means being placed in the vicinity of the pile of articles substantially at the height of the first article in said pile, at least one of the vacuum gripping means and the supplying means being mounted so as to cause relative movement therebetween, said movement commencing by said two means approaching one another when the needle type gripping means has seized and raised the edge close to the supplying means of the first article lying on the pile of articles.
