Claims (1)
上に、用紙との滑りを生じないで接触回転できるように
設けたローラ（半径ｒ）と、前記ドラムの回転角を検出
する検出器と、該ドラムの回転により接触回転する。前
記ローラの回転角を検出する検出器とより成り、前記ド
ラムを所定角θ。回転させたときの前記ローラの回転角
検出値φ□から、あるいは前記ドラムを回転させて前記
ローラを所定角φみ（φｏ＝Ｒθ。）回転させたときの
前記ドラムの回転角検出値θ１からドラム径の変化ΔＲ
を検出することを特徴とするドラム径変化検出装置。A roller (radius r) is provided on the paper wrapped around the drum (radius R) of a drum type drafting machine so that it can rotate in contact with the paper without slipping, and a detection device that detects the rotation angle of the drum. The drum rotates in contact with the drum. and a detector that detects the rotation angle of the roller, and rotates the drum at a predetermined angle θ. From the rotation angle detection value φ□ of the roller when rotated, or from the rotation angle detection value θ1 of the drum when the drum is rotated and the roller is rotated by a predetermined angle φ (φo=Rθ.) Change in drum diameter ΔR
A drum diameter change detection device characterized by detecting.
