Summary:PROBLEM TO BE SOLVED: To provide a device and a method capable of forming a recess in a rubber strip while effectively preventing a damage on the rubber strip.SOLUTION: A device is for forming a plurality of recesses 11 on an outer surface of a rubber strip 10. The device includes: a conveying part 12 configured to convey the rubber strip 10; a roller 13 with a projection 20 formed; a roller support part 14 rotatably supporting the roller 13; and a torque imparting part 15 configured to impart a torque to the roller 13. The roller support part 14 is disposed so as to allow the roller 13 to move at a position to contact with the rubber strip 10 being conveyed. The torque imparting part 15 imparts a torque in advance along a conveying direction of the rubber strip to the roller 13, before the roller 13 has contact with the rubber strip 10 being conveyed.SELECTED DRAWING: Figure 3 【課題】ゴムストリップの損傷を効果的に抑制しながら、ゴムストリップに凹部を形成することができる装置及び方法を提供する。【解決手段】ゴムストリップ10の外面に複数の凹部11を形成するための装置である。ゴムストリップ10を搬送する搬送部12と、突起20が設けられたローラ13と、ローラ13を回転可能に支持するローラ支持部14と、ローラ13に回転力を付与する回転力付与部15とを有する。ローラ支持部14は、ローラ13を搬送中のゴムストリップ10と接触する位置に移動可能に設けられている。回転力付与部15は、ローラ13が搬送中のゴムストリップ10に接触する前に、予め前記ローラ13にゴムストリップの搬送方向に沿った向きの回転力を付与する。【選択図】図3
