Abstract

A twine knotter has a knotter frame (2). An intermediate shaft (3) is rotatably supported on the knotter frame (2) around a longitudinal axis L. A shaft input (4) connects the intermediate shaft (3) to an output element (61) of a knotter drive shaft (54). At least one knotter hook shaft (9, 10) is rotatably supported around a knotter hook axis (K1, K2) on the knotter frame (2). The at least one knotter hook shaft (9, 10) is drive-wise connected to the intermediate shaft (3). The at least one knotter hook shaft carries a knotter hook (11, 12) to form a knot. The twine knotter (1) is formed as an independent assembly. The twine knotter (1) is drive-wise detachably connectable, via the shaft input (4) of the intermediate shaft (3), to the knotter drive shaft (54).
