Abstract:
A method of manufacturing a building panel using a panel crimping machine, comprising:(a) providing two pairs of crimping rollers wherein each pair is separated by a gap, each of said pairs comprising: (1) a male crimping roller comprising a plurality of male crimping blades extending from its center; and (2) a female crimping roller comprising a plurality of female crimping blades extending from its center; (b) rotating both pairs of crimping rollers, whereupon rotating both pairs, said first pair of male and female crimping rollers intersect and crimp a first portion of a panel and said second pair of male and female crimping rollers intersect and crimp a second portion of said panel; (c) simultaneously adjusting the distance between both pairs of crimping rollers using a said gap adjusting mechanism comprising: (1) a motor; (2) a gear box connected to said motor, said gear box having a gear box shaft extending therefrom; (3) a gear box sprocket mounted on said gear box shaft; (4) a first sprocket connected to said gear box sprocket by a first chain, wherein said first sprocket is a double sprocket; (5) a first gear mounted on a shaft connected to said first sprocket; (6) a second gear engaging said first gear, said second gear connected to a support for said first male crimping roller via a threaded shaft such that when said second gear rotates, said threaded shaft causes said first male crimping roller to move toward or away from said first female crimping roller; (7) a second sprocket connected to said first sprocket by a second chain; (8) a third gear mounted on another shaft connected to said second sprocket; and (9) a fourth gear engaging said third gear, said fourth gear connected to a support for said second male crimping roller via an other threaded shaft such that when said fourth gear rotates, said other threaded shaft causes said second male crimping roller to move toward or away from said second female crimping roller as said first male crimping roller simultaneously moves toward or away from said first female crimping roller.
