ABSTRACT:
A harvester for harvesting only the blade or lamina from a mature kelp plant uses a plurality of harvester mechanisms for movement through a kelp bed adjacent the sea bottom. Each mechanism has a pair of helically formed spindles parallel to each other for relative counter-rotation, the helices being of opposite hand. A kelp stipe, encountering the spindles is moved upwardly thereby to bring the attached lamina into a channel forward of the spindles, adjacent which channel a cutter is positioned. When the lamina starts to engage the spindles they separate slightly and operate a linkage which in turn actuates the cutter to sever the lamina. The severed laminae are collected in a basket connected to the harvesting mechanisms. By harvesting only the lamina the plant can regenerate a new lamina and it is possible to have repeated harvests from a single plant.
