And adjusting device for tensioning bands mounted between two pulleys

摘要

1. Device for adjusting and Stretch mounted bands between two pulleys, which being designed for use preferably on machines for working footwear, essentially characterized in that it is constituted from a prismatic piece acting as regulator, which is swingably mounted to move in either direction to one of the pulleys and fixed to the general frame by two screws arranged in facing opposition emerging side and severally such as a plate that is attacked by the end of a stud acting manually operated control knob which cause thrust in either direction of the emerging plate to produce the swiveling of the die and thus the respective lateral displacement of the pulley, in order to produce the regulation or centering of the band itself; it being provided that the regulation tensioning this is done by a manually operated lever, lacual is secured to one end of a plate permanently required by a tension spring with control knob, the other end of said plate hinged to the overall frame while that the end portion on which is secured the said lever is also hinged to the end of a second plate articulated at its other end to a mounted rod between the pulley shaft and the shaft or bolt tilting of given controller such that actuation of the lever and corresponding tilting displacements in the platens, cause the drag pulley, in order to achieve tightening and / or slackening of the band. 2. Adjusting device for tensioning and bands mounted between two pulleys.
