Cutting and rolling device for use with pharmaceutical pouch packaging

A winding mechanism for a machine for cutting and rolling a strip of pharmaceutical pouches, comprising:

• first and second vertical walls, wherein the second vertical wall is spaced apart from and generally parallel with the first vertical wall;
• a member fixed to and spanning the first and second vertical walls to form a frame;
• a spindle rotatably mounted in the first vertical wall;
• a cylindrical body rotatably mounted in the second vertical wall and coupled to the spindle to rotate with the spindle;
• a hub slidably and rotatably mounted on the spindle, the hub including first and second pins that extend into and are slidable relative to the cylindrical body;
• a rotary drive unit mounted to the first vertical wall and coupled to the spindle to rotate the spindle relative to the first and second vertical walls;
• a linear actuator mounted to one of the first and second vertical walls;
• and
• a carriage mounted on the linear actuator for linear movement and slidably mounted on the spindle between the hub and the first vertical wall, the carriage engaging the hub and permitting rotation of the hub relative to the carriage;
• wherein the carriage is movable along the linear actuator between a retracted position, wherein the first and second pins are retracted into the cylindrical body, and an extended position, in which ends of the first and second pins extend beyond the cylindrical body.
