Drinking straw machine informations

The drinking straw machine apparatus according to claim 1 wherein:

there are frictional grip-enhancing features provided on said outer peripheral surfaces of the auxiliary rollers

BACKGROUND OF THE INVENTION： The present invention relates to a packing machine, optionally an attachment for a packing machine, for packing bales of straw fodder of a “rectangular” form the machine comprising two drive rollers which rotate the straw fodder bale around a substantially horizontal axis.

In agriculture, it is becoming more and more common to ensile straw fodder in the form of packed straw fodder bales. There is a movement away from the traditional silo plant.

SUMMARY OF THE INVENTION ：An objective of the present invention is to provide either a new complete packing machine, or optionally an attachment which can be mounted subsequently on machines which already exist, for packing bales of straw fodder which are rectangular in form.

According to the invention, this is achieved by a cutting machine, or optionally an attachment thereto, of the kind described by way of introduction which is characterized in that each drive roller is operationally coupled to two auxiliary rollers.

BRIEF DESCRIPTION OF THE DRAWINGS： The invention will now be described in more detail by means of an embodiment example where the machine is of the kind which is equipped with a swivel arm. The embodiment example is described with reference to the enclosed drawings where:

FIG. 1 shows in perspective a packing machine according to the invention in perspective,

FIG. 2 shows a schematic frontal outline of the packing machine according to FIG. 1,

FIG. 3 shows schematically a rotation sequence of the rectangular bale around the horizontal axis,

FIG. 4 shows a longitudinal section through the drive roller and the auxiliary roller and an end section of the roller unit,

FIG. 5 depicts the previously known packing machine of the kind which has a swivel arm, and

FIG. 6 depicts the previously known spoon-shaped straw machine of the kind which has a swivel table

DETAILED DESCRIPTION： On the back edge of the roller units 4, two support rollers are mounted, to which the fodder bale 5 rests adjacent at the back edge.

FIG. 2 illustrates schematically the packing machine 10 viewed from the front where the straw fodder bale 5 has started its rotational movement. As can be seen from the figure, the fodder bale 5 rests, in this phase, on the all the auxiliary rollers 2.

FIG. 3 shows a rotational sequence through the first 90° of the turning movement of the rectangular bale. This also shows how the roller units 4 work the whole time during the turning of the rectangular bale.

FIG. 4 shows a longitudinal section through the drive roller 1 and the auxiliary roller 2. At the end of each roller, a chain wheel 11 is mounted for the transmission of power to the auxiliary rollers 2.
