Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a high efficiency heat treatment apparatus for curling which performs the curling magnetic tape pieces by heating and the conveyance of them simultaneously and can carry out the curling continuously in large quantities in a limited space and a curling heat treatment system. SOLUTION: A magnetic tape 30 is charged from a hopper in the upper part of a crusher 1 and cut into magnetic tape pieces about 3-20 mm in length. The pieces are conveyed through a pneumatic transportation conduit 3 and supplied from a cyclone 4 to a heating transportation conduit 6. In the conduit 6, the pieces are conveyed while being heated at 140-200 deg.C by a hot air current supplied from a hot air generator 5. The pieces are curled/shrunk by heating from the hot air current to be a raw material for recycling and packed in a container 14 or supplied directly to a panel production process and others for recycling.
