ABSTRACT:
A roll forming machine having a frame defining a roll forming region is provided with an improved twine wrapping mechanism that includes an elongated twine dispensing tube that is adapted to swing across the bale forming region in a predetermined path during the twine wrapping operation. A twine severing means in the form of a striker plate and a movable knife is provided for severing the twine at the completion of the wrapping operation. A latch, movable between tube receiving and tube holding positions is also provided for positively retaining the twine dispensing tube in a rest condition at the completion of the wrapping operation and during the roll forming operation. The latch and the knife are interconnected such that the knife is driven against the striker plate, clamping the twine therebetween, as the twine dispensing tube is driven into the latch forcing the same from its tube receiving to its tube holding position.
