上記の工程により、回転する上下一対のローラ１０ａ、１０ｂを通過する２枚の枚葉紙１４には、切れ目１６と繋ぎ部１８が交互に多数形成され、同時に２枚の枚葉紙１４は連接されるが、連接された長尺の紙製緩衝材２０ａを切れ目１６方向に圧縮することにより、断面形状を略波状にする圧縮手段３４について説明する。 The above procedure, a pair of upper and lower rollers 10a to rotate, the two sheets 14 passing through 10b, cuts 16 and connecting portion 18 are formed a large number alternately, the two sheets 14 simultaneously connected It is the but, by compressing the paper cushioning material 20a of articulated long the break 16 direction, illustrating the compression means 34 for the cross-sectional shape substantially undulating.
上下一対のローラ１０ａ、１０ｂの背面にローラ１０ａ、１０ｂを通過する枚葉紙１４の下面を支持する下部受板２６が設けられている。 A pair of upper and lower rollers 10a, rollers 10a, a lower receiving plate 26 for supporting the lower surface of the sheet 14 passing through 10b are found provided on the back of 10b.
下部受板２６のローラ１０ａ、１０ｂ側は、傾斜部２６ａとして設けられ、一対のローラ１０ａ、１０ｂの接線方向に下方から上方に向けて傾斜され、ローラ１０ａ、１０ｂから送り出される枚葉紙１４の下面を誘導できるように図られている。 Roller 10a of the lower support plate 26, 10b side is provided as the inclined portion 26a, a pair of rollers 10a, is inclined upward from below in the tangential direction of 10b, rollers 10a, 10b from the sheet 14 fed It is achieved to allow induce lower surface.
ローラ１０ａ、１０ｂから遠ざかる下部受板２６の大部分は、水平部２６ｂとして設けられ、枚葉紙１４の下面を支持するようにしてある。 Most of the lower support plate 26 away from the roller 10a, 10b is provided as a horizontal portion 26b, it is then adapted to support the lower surface of the sheet 14.
一方、上下一対のローラ１０ａ、１０ｂの背面にローラ１０ａ、１０ｂを通過する枚葉紙１４の上面を支持する上部受板２８が設けられている。 On the other hand, a pair of upper and lower rollers 10a, rollers 10a on the back of the 10b, the upper receiving plate 28 for supporting the upper surface of the sheet 14 passing through 10b.
上部受板２８は、ローラ１０ａ、１０ｂ側の固定板２８ａとローラ１０ａ、１０ｂから遠ざかる可動板２８ｂから構成されている。 Upper receiving plate 28, and a movable plate 28b away from the rollers 10a, 10b side of the fixed plate 28a and the roller 10a, 10b.
固定板２８ａは、前記した下部受板２６の傾斜部２６ａと対称に傾斜し、ローラ１０ａ、１０ｂの接線方向に上方から下方に向けて傾斜され、ローラ１０ａ、１０ｂから送り出される枚葉紙１４の上面を誘導できるように図られている。 Fixing plate 28a is inclined to the inclined portion 26a and the symmetry of the lower support plate 26 described above, the roller 10a, is inclined obliquely towards the top to bottom in the tangential direction of 10b, the sheet fed out roller 10a, from 10b It is achieved as capable of inducing upper surface 14.
これに対して、可動板２８ｂは、固定板２８ａ側において軸３０を介して軸３０を基軸として上下方向に回動自在に枢着されている。 In contrast, the movable plate 28b is rotatably pivoted in the vertical direction axis 30 as a key via a shaft 30 in a fixed plate 28a side.
また、可動板２８ｂの先端部上には分銅３２が載置されている。 Further, weight 32 is placed on the on the distal end portion of the movable plate 28b.
そこで、前記した圧縮手段３４により、長尺の紙製緩衝材２０ａを圧縮させることにより、断面形状が略波状である長尺の紙製緩衝材２０Ａ（図５を参照）を得る方法について説明すると、ローラ１０ａ、１０ｂから送り出された長尺の紙製緩衝材２０ａは、ローラ１０ａ、１０ｂ側に設けられた下部受板２６の傾斜部２６ａと上部受板２８の固定板２８ａにより誘導されつつ、下部受板２６と上部受板２８の前方に向けて繰り出されるが、このとき、上部受板２８の可動板２８ｂは、前記した軸３０を介して上方に向けて浮き上がるように回動する。 Therefore, the compression means 34 described above, by compressing the paper cushioning material 20a long, explaining how the cross-sectional shape obtaining elongated paper cushioning material 20A which is substantially wavy (see Figure 5) , rollers 10a, elongated fed from 10b paper cushioning material 20a, the roller 10a, while being guided by the fixed plate 28a of the inclined portion 26a and the upper receiving plate 28 of the lower support plate 26 provided on the side 10b, Although drawn out toward the front of the lower support plate 26 and the upper receiving plate 28, this time, the movable plate 28b of the upper receiving plate 28 is rotated so lifted upward through the shaft 30 described above.
一方、可動板２８ｂは分銅３２が載置されることにより、自由に回動することなく、過度の浮き上がりが抑制される。 On the other hand, the movable plate 28b is that the weight 32 is placed, freely without rotation, excessive lifting is prevented.
かくして、ローラ１０ａ、１０ｂ間を通過した長尺の紙製緩衝材２０ａは下部受板２６の水平部２６ｂと上部受板２８の可動板２８との間を自由に通過することなく、可動板２８と分銅３２の重力の作用を受ける。 Thus, the roller 10a, the paper cushioning material 20a elongated passed between 10b freely without passing between the movable plate 28 of the horizontal portion 26b and the upper receiving plate 28 of the lower support plate 26, the movable plate 28 subjected to the action of gravity of the weight 32.
この結果、下部受板２６と上部受板２８の前方側において繰り出し応力を受けつつある長尺の紙製緩衝材２０ａに緩いながらブレーキがかかることになり、下部受板２６と上部受板２８の前方側に近い位置ほど強制的に凝集状態を構成する。 As a result, it takes a loose while brake elongated paper cushioning material 20a that is being subjected to feeding stress at the front side of the lower receiving plate 26 and the upper receiving plate 28, the lower receiving plate 26 and the upper receiving plate 28 constitute forcibly aggregated state as a position closer to the front side.
このようにして、長尺の紙製緩衝材２０ａを切れ目１６方向に圧縮することを機械的に実施でき、断面形状が略波状である長尺の紙製緩衝材２０Ａを得ることができる。 Thus, compressing the paper cushioning material 20a is elongated in the slit 16 direction mechanically be performed, it is possible to cross-sectional shape obtaining elongated paper cushioning material 20A which is substantially wavy.
可動板２８ｂ上の分銅３２の載置位置を変更させることにより、長尺の紙製緩衝材２０ａに対する重量を増加させ、あるいは減少させることにより、長尺の紙製緩衝材２０ａに対する負荷を調整して、断面形状における波の大小を変更できる。 By Ru is changed mounting position of the weight 32 on the movable plate 28b, by increasing the weight for the paper cushioning material 20a long, or decreasing, adjusting the load on the elongated paper cushioning material 20a to, can change the wave magnitude in the cross-sectional shape.
