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.

Coiler spool with built-in gripper slot

In the rolling of e.g. metal strip, an entry reel is provided in the form of a stub mandrel having two opposed and spaced-apart arms with reduced diameter end portions, rolling the strip and evacuating a tail end of the strip from the entry reel, placing a coiling spool over the reduced diameter portions of the arms of the stub mandrel, reversing the rolling direction of the mill, gripping the last rolled end of the strip on the coiling spool, again rolling the strip, and coiling the rolled strip on the coiling spool.
