PROBLEM TO BE SOLVED: To provide a molding apparatus and a molding method which can improve production efficiency of a molding.SOLUTION: A molding apparatus 1 executes carrying molding processing so as to synchronize with a shot ST1 of a continuous sheet SH1 and includes a molding portion U1 which molds a sheet in every shot ST1, carrying means of carrying a sheet in the carrying direction D1 passing through the molding portion U1, sheet detection portion U3 of detecting a sheet at an upstream position in the carrying direction D1 for carrying from the molding portion U1 and control means of starting carrying molding processing after the starting edge part is carried in the carrying direction D1 from the upstream position when the starting edge part of the sheet is detected in the sheet detection part 3. When the end edge part of the sheet is detected in the sheet detection portion U3, the control means stops molding of the sheet after the end edge part is carried from the upstream position in the carrying direction D1 or carries the sheet in the carrying direction D1 at the slower speed during the standby time after the end edge part is carried from the upstream position in the carrying direction D1 at the carrying speed during molding. 【課題】成形品の製造効率を向上させることが可能な装置および成形方法を提供する。【解決手段】連続したシートSH1のショットST1に合わせた搬送成形処理を行う成形装置1は、シートをショットST1毎に成形する成形部U1と、該成形部U1を通る所定の搬送方向D1へシートを搬送する搬送手段と、成形部U1から搬送方向D1の上流位置でシートを検出するシート検出部U3と、該シート検出部U3でシートの始端部が検出されたとき該始端部を上流位置から搬送方向D1へ搬送させた後に搬送成形処理を開始させる制御を行う制御手段と、を備える。制御手段は、シート検出部U3でシートの終端部が検出されたとき、該終端部が上流位置から搬送方向D1へ搬送された後にシートの成形を停止させたり、あるいは終端部が上流位置から搬送方向D1へ成形時の搬送速度で搬送された後により遅い待機時の搬送速度でシートを搬送方向D1へ搬送させる。【選択図】図３
