PROBLEM TO BE SOLVED: To provide a film feeding apparatus in which the drawing resistance of a film drawn out from a film roll can be kept constant irrespective of the amount of winding, the apparatus being capable of coping with a film having a wider width than the conventional apparatus.SOLUTION: According to the present invention, there is provided a film feeding apparatus. In the apparatus, a spring is attached so that a force acts in a direction in which a film roll 1 is pressed and urged by a receiving roller 2. A turning portion including a roll stay and the film roll 1 is brought into close contact with a receiving roller 2 by the action of the spring in addition to their own weights. The film 4 is pulled out from between the film roll 1 and the receiving roller 2, and is led to the rear of a constant-pressure wheel 17 via a resistance roller and a push-out roller 3, followed by being laid by advancing the tractor 12.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】フィルムロールから引き出されるフィルムの引き出し抵抗を、巻き量の多少にかかわらず一定に保つことができる上、従来の装置よりも幅の広いフィルムに対応することができるフィルム繰出し装置を提供する。【解決手段】フィルムロール1が受けローラー2に押圧付勢される方向に力が働くようにスプリングを取付け、ロールステーおよびフィルムロール1からなる回動部分を、自重に加えてスプリングの働きにより受けローラー2に密着させる。フィルムロール1と受けローラー2の間からフィルム4を引き出し、抵抗ローラーとツキダシローラー3を経てトウアツリン17の後方へ導き出し、トラクター12を前進させながらフィルム4を敷設することを特徴とした、フィルム繰出し装置。【選択図】図1
