parallel to the table 1 and having on its edge turned towards
the rake 3 cut-outs 42, each having a profile capable of
surrounding a part of the case 2. The retractable guide bar 5
is mounted on the end of a support 11 hinged on a pivot 12
fixed to the table 1, the bar 5 being maintained in the normal
position by the action of a spring 13 and by the adjustable
stop 25. The straight edge 6 is fixed on bearings 14 by means
of adjusting screws 15. Holes 16 are provided in the straight
edge 6 in order to adjust its
position in relation to the position of the cases 2.
Lachaussee teaches that the matrix bar 4 and the rake 3
are actuated by cam mechanisms mounted on a camshaft 10
running along the table 1. The mechanism controlling the
matrix bar 4 can
be seen in Figure 1, while the mechanisms controlling the rake
3 are shown in Figures 4 and 5. The matrix bar 4 retains all
the cases 2 in its cut-outs 42, the cases being backed up by
the straight edge 6. The guide bar 5 runs opposite the bearing
line of the rake 3 against the cases 2. Each case is thus
held at at least four points, thereby ensuring accurate
