<p>A clamp is shown for holding a log of paper while a log-saw or cutting machine cuts shorter lengths of toilet-paper rolls or rolls of kitchen towels or similar all-purpose wipers from the log. The clamp is arranged adjacent a seat or support for the log as well as adjacent a cutting blade. The clamp includes, for each log seat, and on opposite sides of a cutting plane (T-T) through which the blade passes, a pair of adjustable and symmetrically arcuate strips (212, 214) secured to supports (207, 209). The strips are of flexible material with end portions which tend to spring outwardly. A strap (222) is anchored to a retention holder (224) and an adjustment holder (246). The strap surrounds the pair of strips (212, 214) and can change the arrangement thereof. A drive (240, 262, 218) simultaneously adjusts both the length of the strap (222) and the symmetrical angular orientations of two appendixes (228A; 228B) and, consequently, of two cradles (518) on which the strips are supported. <IMAGE></p> |
