Claims10
A method of handling and drying cardboard tubes, comprising:
- receiving the cardboard tubes in a horizontal orientation at the exit of a conveyor, the cardboard tubes being wet from a previous winding and gluing process, and having a given moisture level;
- stacking the cardboard tubes vertically on a skid to form a stack, said skid having a top face supporting the stack and bottom face facing the ground, the skid being traversed by channels or openings extending from the top to the bottom face allowing air to circulate therethrough, the stack having bottom, top and lateral sides;
- placing the skid supporting the stack into a dryer, the air flow circulating through the skid and cardboard tubes, and drying the stack by circulating air in the dryer for a predetermined period of time, lowering the moisture level of the cardboard tubes;
- and
- sealing at least the bottom, top and lateral sides of the stack at the exit of the dryer by wrapping the stack with a plastic film while keeping the stack on the same skid used for drying the stack.
