And it is easy to stabilize the folding operation of the continuous body, thereby providing a continuous folding device and a folding method. A conveying section having a moving surface which moves while sucking and holding the first region (2a) of the continuum (2), and which conveys the continuum (2) in the longitudinal direction of the continuous body (2), and a moving section A first endless belt (31) moving along a first virtual surface in a first circulation path moves a first reference section (31 x) adjacent to a virtual line (2 x) of a continuum (2) A first folding reference portion moving along the same direction as the surface at the same speed and a second folding reference portion disposed along the first reference section and overlapping the second region of the continuum, In the cross section perpendicular to the imaginary line (2 x) of the continuum (2), the angle formed by the first region (2 a) and the second region (2 b) is conveyed to the downstream side in the conveying direction Folding the continuum (2) with the imaginary line (2 x) as a reference so that the second region (2 b) faces toward the first region (2 a) A first guide member for moving Te comprises a.連続体を折る動作を安定させることが容易である、連続体の折り装置及び折り方法を提供する。 連続体(2)の第1領域(2a)を吸着保持しながら移動する移動面を有し、連続体(2)を連続体(2)の長手方向に搬送する搬送部と、移動面を含む第1の仮想面に沿って第1の循環経路を移動する第1の無端ベルト(31)が、連続体(2)の仮想線(2x)に隣接する第1の基準区間(31x)を移動面と同じ方向に同じ速度で移動する、第1の折り基準部(30)と、第1の基準区間(31x)に沿って配置され、連続体(2)の第2領域(2b)に当接し、連続体(2)の仮想線(2x)に垂直な断面において第1領域(2a)と第2領域(2b)とのなす角が、連続体(2)が搬送方向下流側に搬送されるにしたがい小さくなるように、仮想線(2x)を基準に連続体(2)を折り、第2領域(2b)を第1領域(2a)に向けて移動させる第1の案内部材と、を備える。
