From 1 and 2 the work passes to the second pair of feed rolls 3 and 4, c and d being the intermediates.
Similarly 5, 6, 7 and 8 are feed rolls, and e, f, g, h intermediates. The first head is shown at k′, the side heads at h, and the last head at i′, the latter being carried on a sliding head j, which is secured in its adjusted position by nuts i. On the side of the frame d on which j slides is a graduated index to denote the adjustment of the head i′.
Fig. 3184.
The construction of the parts in immediate connection with the front cutter head is shown in [Fig. 3184]. n is the frame corresponding to n in [Fig. 3183], the rolls 5 and 6 also corresponding in the two figures.
Upon n is a slide s having an arm g, carrying the roll g′, which holds the timber down to the cut of the cutter head k′. The pressure of roll g′ to the work is given through the medium of the rod a′, which receives the pressure of the equalizing bar x, [Fig. 3183].
