Posted on by admin

The Newlong CM4900-3 infeeder from Newlong Industrial infeeds the bag into the Sewing head such as the Newlong Industrial DS-9C series. It cuts the top of the bag automatically and applies crepe tape. In this way you wil always have a perfect application of the Crepe tape. The crepe tape reduces sifting (leaking) of the product through the needle holes. The crepe tapes gives a nice and polished and presentable product. Ideal for all products such as Animal feeding products, sugar, Flower and simular powderish products.
