Clamp

This mechanism is for clamping sheet 1 around drum 2, formed with recess
3. Disposed in recess 3 and rigid with drum 2, is clamp bar 4 having V-shaped groove 5. Rotary mounted in recess 3 is clamp bar 6 having an L-shaped groove
7.

Toggle bar 8 having V-shaped edge 9 and rounded edge 10 extends along the axial length of drum 2 and coacts with grooves 5 and 7 of bars 4 and 6. Extensions 11 on each end of bar 8 project beyond V-shaped edge 9 and between guide pins 12 on ends 13 of bar 4.

To attach sheet 1 to drum 2, one end 14 is inserted between groove 5 of bar 4 and edge 9 of bar 8. The other end 15 of sheet 1 is inserted between groove 7 of bar 6 and edge 10 of bar 8. By rotating bar 6 in the direction of arrow 16, bar 8 is cammed in the direction of arrow 17 and sheet 1 is drawn taut around drum 2.
