ABSTRACT:
Strap binding apparatus is disclosed as including a traction wheel (2T) and a back-up wheel (2B) wherein the traction wheel (2T) is rotatably mounted upon an axis (t) which is fixed within a binding head framework, while the back-up wheel (2B) is rotatably mounted upon an axis (b) which is eccentrically disposed, by means of an eccentric shaft (10), with respect to a base axis (X) through means of an eccentric distance (x). A support plate (9) is pivotably mounted within the binding head framework about the axis (t) and is biased in its pivotable movement by means of a spring (8) interposed between the support plate (9) and the binding head framework. A lever (10a) is mounted upon the eccentric shaft (10), and a linkage member (11) has one end thereof connected to the lever (10a) and the other end thereof connected to the support plate (9) such that upon pivotable movement of the support plate (9) under the biasing influence or force of the spring (8 ), the back-up wheel (2B) is rotated into engagement with the traction wheel (2T). The degree to which the back-up wheel (2B) is rotated into engagement with the traction wheel (2T) is adjustable either by changing the length of the linkage member (11) or by altering the connection location defined between the lever (11) and the support plate (9) at any one of the plurality of holes (9a) formed within support plate 9.
