To provide a rubber coating device and rubber coating method in which a thermal shrinkage of a cord due to heat and a significant decrease in rubber adhesive strength due to precipitation of sulfur in a rubber due to cooling are unlikely to occur, even if the rubber coating device is stopped for a long time for changing a type of the cord or the rubber.SOLUTION: A rubber coating device that coats multiple cords that have been aligned with unvulcanized rubber includes: drying means for drying the cord with multiple heating rolls; rubber coating means for crimping the unvulcanized rubber to the cord and coating the unvulcanized rubber; cooling means for cooling the rubber-coated cord formed by the rubber coating process with multiple cooling rolls; first separating means for separating each heating roll and the cord; and/or second separating means for separating each cooling roll and the rubber-coated cord.SELECTED DRAWING: Figure 1 【課題】コードやゴムの種類を変更するためにゴム被覆装置が長時間停止した場合でも、熱によるコードの熱収縮や、冷却によるゴム内の硫黄の析出によるゴムの粘着力の大きな低下が生じ難いゴム被覆装置およびゴム被覆方法を提供する。【解決手段】引き揃えられた複数本のコードに未加硫ゴムを被覆するゴム被覆装置であって、複数の加温ロールによりコードを乾燥させる乾燥手段と、未加硫ゴムをコードに圧着し、未加硫ゴムを被覆するゴム被覆手段と、ゴム被覆工程により形成されたゴム被覆コードを複数の冷却ロールにより冷却する冷却手段とを備え、各々の加温ロールとコードとを離間させる第１の離間手段、および／または、各々の冷却ロールと前記ゴム被覆コードとを離間させる第２の離間手段を備えているゴム被覆装置。【選択図】図１
