Rotary cutter handling system

A sheeting head comprising:

• a front roller;
• a back roller adjacent the front roller;
• a rotary cutter carried by a cutter carriage;
• and
• sliding means disposed adjacent to ends of the rotary cutter for slidably supporting the cutter carriage between an operating position and a cutter replacement position,
• the cutter carriage comprising:
• two carriage side pieces disposed near either end of the rotary cutter, each in proximity to one of the sliding means;
• an elongate cross-member joining the carriage side pieces to form the cutter carriage;
• bearing means disposed on each carriage side piece for slidingly carrying each carriage side piece along its proximate sliding means;
• and
• attachment means on each carriage side piece for removably attaching one of the ends of the rotary cutter;
• whereby the cutter carriage can be slid from the operating position where the rotary cutter is engageable with the front roller to the cutter replacement position where the rotary cutter is free of the rollers and can be readily removed from the attachment means.
