first transfer means which cause said compacted body to be transferred from said preconsolidating box to said guide box; d.

second transfer means which cause said compacted body to move in a stepwise manner within said guide box; and e.

a preconsolidating box in which scrap may be preconsolidated to a compacted body, said preconsolidating box having a movable lid, one movable sidewall and a base in the form of a slide or shutter for discharge of the compacted body; b.

When the hydraulic rams are retracted, the space for filling in the loose scrap is free and the scrap is then reduced to the required dimensions of the compacted body corresponding to the space B by operating the rams.

The base 4 of the preconsolidating box A does not take the form of a fixed component but of a slide so that it can be withdrawn upon completion of the preconsolidating operation and the preconsolidated body can be allowed to pass into a second box C, located immediately below the box A, at one open end of which are positioned the scrap shears D which preferably take the form of guillotine shears and comprise an upper blade 7, which moves vertically downwards, and a fixed lower blade 8. 2 shows the loading or open position of the precon solidating box A in which the sidewall 2 is retracted and the cover 3 is swung up.
