A side trimmer shear for metallic strip and the like travelling along a pass line including gear housings on opposite sides of the strip as it passes along the pass line. Means are provided for varying the angular positions of the gear housings with respect to the pass line. Upper and lower shear knives are carried on the gear housings for engaging and trimming the edges of the strip; while a rigid shaft extends between the gear housings. Gearing is carried within the gear housings for driving the shear knives; while a gear mounted on splines on the drive shaft is provided with gear teeth with curved side walls which permit angular variation of the positions of the gear housings with respect to the rigid drive shaft. The apparatus also includes chopper rolls carried on the gear housings which are driven by a similar rigid drive shaft and a gear provided with curved side walls. Since the gear on the drive shaft is connected to the drive shaft through a splined connected, movement of the gear housings toward or away from each other is facilitated to accommodate varying strip widths.
A side trimmer for metallic strip travelling along a pass line comprising gear housings on opposite sides of the strip as it passes along the pass line, means for varying angular positions of said gear housings with respect to said pass line, upper and lower shear knives carried on said gear housings for engaging and trimming opposed edges of said strip, a rigid drive shaft extending from one of said gear housings to the other one of said gear housings and carried within aligned bearings, gears carried on said drive shaft within the respective housings and having gear teeth with curved sidewalls to permit angular variation of the positions of the gear housings with respect to the said pass line without disturbing the alignment of said rigid drive shaft within its bearings, and gearing within said housings connecting said gears with curved sidewall gear teeth to said shear knives.
