PROBLEM TO BE SOLVED: To achieve both securement of quality of a manufactured transmission belt and facilitation of a stripping step.SOLUTION: A drum 10 including three circular arc pieces 11a-11c is adopted. In a stripping step, at least one (the circular arc piece 11b or 11c) of the circular arc pieces 11a-11c is moved to the radial inside of the drum 10, and a sleeve 1 is taken out by bringing the sleeve 1 into noncontact with an outer peripheral surface 10a of the drum 10.SELECTED DRAWING: Figure 5 【課題】製造される伝動ベルトの品質確保と脱型工程の容易化とを共に実現する。【解決手段】３つの円弧片１１ａ〜１１ｃを含むドラム１０を採用し、脱型工程において、円弧片１１ａ〜１１ｃのうちの少なくとも１つの円弧片（円弧片１１ｂ，１１ｃ）をドラム１０の径方向内側に移動させ、スリーブ１をドラム１０の外周面１０ａに接触しない状態としてスリーブ１を取り出す。【選択図】図５
