Abstract

A double-knot twine-knotter unit with twine tying having a plurality of double-knot twine knotters combined on one knotter drive shaft. Each double-knot twine knotter comprises at least one knotter drive disc, a knotter chassis, a knotter assembly and a blade lever. The knotter drive disc is fastened fixedly on the knotter drive shaft which can be driven about its axis. The knotter chassis carries a knotter assembly, which forms two knots following one another, and the blade lever which is driven by a cam track of the knotter drive disc. The knotter assembly is arranged so as to overlap in the axial direction of the knotter drive shaft with the knotter drive disc of the adjacent double-knot twine knotter on a part length of the knotter assembly.
