专利汇可以提供Automatic bag neck gatherer and tying mechanism专利检索，专利查询，专利分析的服务。并且This invention is concerned with the subject matter of placing a tie upon the neck of a bag that has previously been filled. The bags for which this particular device is designed are the type that utilize food stuffs, particularly popcorn, potato chips, apples, oranges, onions and the like. There is a source of tie wire which is free mounted. The wire is fed through certain tubes that are strategically located in designated areas. The wire that is pulled through the tubes is bent. One of the tubes is moveable and because the wire is bent, the wire can be pulled from its source through the fixed tube. There is a spinning type of knife which cuts off a segment of the wire. The cut off wire is then wrapped around the neck of the bag. The neck of the bag is squeezed together by the mechanism. There is a control circuit electrically operated for synchronizing the various function of the device. In the preferred embodiment, pneumatic cylinders are employed for actuating the mechanism. The device has been particularly designed to operate with a filled bag on the Bodolay bag making and feeding machine known as U.S. Pat. No. 2,877,609. There is a tying mechanism that takes the cut wire and wraps around the neck of the bag and the spinner mechanism twists it twice after the neck of the bag has been squeezed snugly together.，下面是Automatic bag neck gatherer and tying mechanism专利的具体信息内容。
