Abstract
A coiler spool comprises an elongated, hollow cylinder made of resilient spring steel and having a slot extending longitudinally of the cylinder, and means, such as an expandable mandrel, to radially expand the coiler spool to open the normally closed slot for reception in the open slot of a leading edge of a strip to be coiled. On release of the coiler spool expansion pressure, the coiler spool contracts due to its inherent resiliency and closes the slot, thereby gripping in the slot the leading edge of the strip to be coiled.
