Title: Werner Graber: Innovator in Winding Technology
Introduction
Werner Graber is a notable inventor based in Horgen, Switzerland. He has made significant contributions to the field of winding technology, holding a total of 3 patents. His innovative designs have improved the efficiency and functionality of various winding apparatuses.
Latest Patents
One of Graber's latest patents is a winding device designed for a lap winding apparatus. This invention allows for the production of a batt lap by winding the batt onto a tube that is rotatable about a fixed axis. The tube is driven by a revolving endless belt, which is arranged in a loop formed between two deflecting rolls and is tensioned by a tensioning device. The design ensures that the loop at the beginning of the lap winding process embraces the tube over an initial minimum wrapping angle of at least 120 degrees, preferably 180 degrees or more. Additionally, the tensioning device is associated with a control device to generate a tensioning force that depends on the lap diameter.
Another significant patent by Graber is an apparatus for extracting bobbin tubes from a magazine. This invention features a gripper that moves in a path transverse to the bobbin tube supports of the magazine, aligning with a bobbin tube. The gripper employs gripping elements that engage a limited arcuate accessible portion of a bobbin tube with sufficient force to extract it during the gripper's movement to a retracted position. After release, a transfer chute directs the bobbin tube to a receiving apparatus for subsequent delivery to a machine.
