This invention provides apparatus for slowing down the forward speed of severed head pieces or sample pieces issuing from a rolling mill at rolling mill speed, so that the severed pieces may be removed from the main processing line. This is achieved by providing a separate channel or track which may be switched into and out of the main processing line to receive the severed pieces, with the switching channel being in the form of a loop. Because of this shape, the forward speed of the pieces is reduced rapidly in a switching channel requiring very little space, not only because of its shape, but also because the curved course of the channel increases frictional engagement with the severed pieces, as opposed to a straight switching channel. |

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Referring to the drawings, in which like reference characters refer to like parts throughout the several views thereof, in FIg.
1, 1 is the funnel-shaped opening for receiving the head or sample pieces S moving in the direction of arrow A, and 5 is the main conveyor for the processing line.
Brake loop 2 may be comprised of individual segments 3.
The brake surfaces of brake channel 2 are indicated at 9.
At the inlet of channel 2, brake surfaces 9 are bevelled, as shown, at 8.
Brake segments 3 may be held onto the frame of channel 2 by appropriate means, such as bolts 10.
6 and 7 indicate drive elements for removing any remaining head pieces or samples S from channel 2.
The runways or tracks on which the brake flute 2 may be displaced laterally at right angle to main conveyor 5, are indicated at 4.
They act as a guide for supporting wheels 11 running on it.
In FIG.
2, 9b indicates the brake surfaces for flat and square profile pieces, and 9a those for round profile.
In operation, the head and sample pieces S to be decelerated enter into funnel 1 and are guided to brake flute 2.
Due to centrifugal force, head and sample pieces S are pressed against brake surfaces 9.
Thus, they are slowed down due to the frictional engagement.
Brake channel or flute 2 is displaced laterally at right angles to the direction of movement, so that either round profiled pieces are brught into alignment with brake surface 9a, or flat and square profiled pieces, respectively, with brake surface 9b.
Displacement is effected on wheels 11 running on the tracks 4.
In the case of head or sample pieces which, due to their low arrival speed, do not require any particular deceleration, brake flute 2 is displaced out of alignment, so that moving conveyor 5 transfers the material further along in the line without engagement with flute 2.
Head and sample pieces which do not run the entire length of the brake channel on their own, are moved out by drive element 6 and guided onto the moving conveyor by drive element 7
