ABSTRACT:
Apparatus for bunching vegetables having a stalk comprising a frame, a chain formed into an endless band, a motor mounted to the frame for recirculatingly driving the chain in a generally elongated loop, a plurality of members affixed to the chain, each member including a vegetable holding portion and a clamping portion, the holding portion being capable of supporting a plurality of heads of vegetables with their stalks extending in a direction generally normal to the plane of the loop, the clamping portion being movable between an open and a closed position such that when it is in the open position vegetables are able to be placed in the holding portion and when it is in the closed position it clamps the stalks of the vegetables in the holding portion, a cam plate connected to the frame and disposed in the path of the clamping portion for moving the clamping portion from the open to the closed position, and a rotary saw for removing portions of the stalks when the clamping portion is in the closed position, whereby when the chain is driven and after vegetables are inserted into the holding portion, the cam plate engages the clamping portion and moves it from the open to the closed position so that continued movement of the chain drives the clamped stalks past the saw which in turn removes undesired portions of the stalks so as to form the vegetables into a predetermined length and hence enables the stalks to be bound with an elastic band that serves to maintain the vegetables in a bunch, and whereby when the clamping portion moves into the open position out of engagement with the cam plate, the bunch of vegetables is capable of being removed from the holding portion, and a method therefor.
