disposed on two crossbraces 8. The two sidewalls 1, 2
are interconnected by a table top 9 from which projects
a stop 10 against which the open ends of the goods 11
abut as they are fed toward the stop 10. On the under
side of table top 9 is provided a drawer 12 which serves
for receiving broken goods 11 from table top 9. As
shown in FIG. 2, table top 9 has a slot 13 through which
the broken goods can enter drawer 12. The entire ap
