Since'the 1,-nives d move in a s shoiil traight line dur,,ng the cutting, operation and thus cut the tufts at a, iini 'f orm height, the I)ott4om portion of the chain which carries those knives which take part in the actual cutt,ing operation: is guided so that it:will not sag,, and for this purpose a bar 66 is attached to @the angle portion 67 of I)ar 13, @ t-he bar 66 having a portion 68 -Nvhi ch underl.ies the lower stretch of the chain and terminates in an upstanding flange 69, the upper surface of which is ma4@hined and provides a si-ipport for the chain.
