Abstract

A body and method for adjusting tension in springs are disclosed. The body is formed for attachment to a primary attachment portion of a collar system and comprises complementary engagement means on its inside and holes propagating from the outside towards the inside of the body, the holes being arranged for receiving an alternative tension adjusting tool, such as an iron bar. The method, for adjusting tension in springs mounted upon rotatable shafts, comprises attaching the body in splined engagement to a collar rotatably mounted upon said shaft, providing a tension adjusting tool, such as an iron bar, in said holes of said body, and winding said collar by winding said body using said tension adjusting tool.
