PROBLEM TO BE SOLVED: To provide a ridge forming machine in a ridge forming range between ridge forming maximum height of machine specification set in advance and minimum height thereof, which can compress and shape one lateral face of a ridge by using a plurality of pressing parts and pressing plate bodies of a lateral face ridge forming body, and form a ridge in the ridge forming range between the maximum height and the minimum height without exchanging the lateral face ridge forming body.SOLUTION: A ridge forming machine is given in which: a rotation axis P1 of a lateral face ridge forming body 13 is arranged in nearly parallel with one lateral face W2 of a ridge W front parts of a plurality of elastic pressing plate bodies G with its length from a pressing part at a front position in a rotation direction toward an adjacent pressing part at a rear position in the rotation direction are arranged at respective pressing parts K and a vertical dimension L of the pressing plate body in the rotation axis P1 is defined according to a ridge forming range between ridge forming maximum height of machine specification and minimum height thereof.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2019,JPO&INPIT【課題】予め定められた機械仕様における整畦可能な最大高さと最小高さとの間の整畦範囲において、側面整畦体の複数個の圧締部及び圧締板体により畦の一方側面は締圧整畦され、側面整畦体を交換することなく最大高さと最小高さとの間の整畦範囲内の畦を整畦することができる整畦機を提供する。【解決手段】側面整畦体13の回転軸線P1は畦Wの一方側面W2に略平行に配置され、各圧締部Kに回転方向前方位置の圧締部から隣り合う回転方向後方位置の圧締部に至る長さの可撓弾性をもつ複数個の圧締板体Gの前部が配置され、圧締板体の回転軸線P1方向の縦寸法Lは機械仕様の整畦可能な最大高さと最小高さとの間の整畦範囲に応じて定められている。【選択図】図6
