Abstract
A support shaft to efficiently fix a roll of material thereon. The support shaft includes a core support roll having a plurality of axial guide grooves formed in an outer periphery thereof. Each guide groove has a tapered bottom sloping outwardly. In each guide groove is inserted a slider plate having a tapered side and biased inwardly by a ring coil spring provided around the slider plates. A knob is inserted in the core support roll at one end thereof. The knob has a radially outwardly extending guide pin inserted in an inclined guide hole formed in the core support roll. By turning the knob, the guide pin is moved along the guide hole. The knob is thus moved axially, so that the slider plates are pushed axially, thus causing the slider plates to move along the tapered bottoms of the guide grooves and also move radially outwardly to press against the inner surface of the roll.
