Abstract
A break roll machine wherein a timing belt of a differential transmission mechanism can be removed easily and wherein the removal of a roll pack module from a machine frame and the installation of the new pre-assembled roll pack module can be performed easily in a short time is disclosed. A cutout portion is provided to one of a paired tension arms so that the one tension arm is rotatable around a pivot point at an upper portion of the tension arm. As a rotary shaft of an idler pulley is released from the tension arm through the cutout portion, the timing belt can be removed easily. An air cylinder is rotated freely by a first and a second linkage member. An operator can easily access to a bolt located behind the air cylinder only by inclining the air cylinder at any desired direction.
