The bars (28, 30) are clamped to bar support beams (78, 79) without the need for bolts to extend through individual bars.

The bars are produced by infiltration.

The plurality of rungs are spaced along the rails to define a plurality of openings between adjacent rungs.

The apparatus includes two laser diode bars (22,24) and a mirror arrangement (26) placed between the laser diode bars.

The grid assembly (28) includes a plurality of grid bars (28a, 28b) connected to frame (13) in a spatial relationship such that any two contiguous grid bars (28a, 28b) are separated by a grid space.

The bars (16) penetrate directly into the cover (23).

The rungs (12) are coupled to the endrings (16) by connector portions (14), which create a gap between the endrings (16) and the rungs (12).

Once the beehive is assembled, the bars are located beneath the frames.

A removeably mounted screenfield bar retainer (41) at each holder attaches the bars.

The crossbars (1) are horizontally fixed on the connection holes (7).

And the cages are so big there is no room between them.

When each set is in its relatively high position, the bars are moving longitudinally toward the infeed end of the bar screen (10).

The bars of the grid shall be parallel to the longitudinal axis of the grid.

The ladder stiles having cut outs (23) to receive the bars so that the ladder section rungs (22) and frame bars (12) form alternate rungs of the frame ladder.

The magnet bars (9) and holder sleeves (14) are individually accessible.
