Problems solved by technology
It has been found that because of the extent to which the wrapping film has been stretched around the circumferential surface of the bale, the impact of a circumferentially wrapped bale with the ground as the bale is being discharged from the baler can cause the wrapping material to sever, resulting in unraveling. and disassembled the bundle

Embodiment Construction
[0095] With reference to the attached drawings and first to the Figure 1 to Figure 7 , shows a baler according to the invention, generally indicated by reference numeral 1, for forming forage material such as pasture, hay, straw, silage, etc. into cylindrical bales 2, said cylindrical bales The bag 2 is wrapped circumferentially with a wrapping material, which in this embodiment of the invention comprises a plastic film wrapping material 3 . The rolled bale 2 typically has a diameter of about 1.3 meters and an axial length of about 1.25 meters, but the rolled bale may have a diameter in the range of 1 to 1.8 meters. The wrapping film 3 is a pre-stretched polyethylene film of the type disclosed in PCT specification No. WO 2011 / 076694 and is coated on one surface with a photoself-adhesive coating. Typically, the wrapping film 3 is fed in a roll 4 and in this case has a width of about 1.4 meters and a thickness of about 20 microns. However, depending on the size of the bale, t...

A fixed chamber baler (1) with a bale forming chamber (12) comprises a system for controlling the degree of stretching along the feed direction of the wrapping film (3) wrapping the bale (2), in which A bale (2) of silage is formed in the bale forming chamber and the bale of silage is wrapped around the circumference with a wrapping film (3). The system comprises: a first rotary encoder (51) for monitoring the rotational speed of the bale turning roller (18e) of the baler (1); and a second rotary encoder (54) for monitoring the The rotational speed of the tension roller (32) that tensions the wrapping film (3). The microprocessor (56) calculates the line of the wrapping film (3) near the rotating bale (2) and tension roller (32) from the signals read by the first and second rotary encoders (51, 54). The ratio of the speed difference to the linear speed of the wrapping film (3) in the vicinity of the tension roller (32) as the wrapping film (3) is being wrapped onto the bale (2) The value of the degree of stretch introduced in the film. The torsional load applied to the tension roller (32) is varied for varying the rotational speed of the tension roller (32) until the degree of stretch that the wrapping film (3) is applying to the rotating bale (2) is equal to that stored in micro Until the predetermined degree of stretching in the processor (56).
Description
technical field [0001] The present invention relates to a method and system for circumferentially wrapping a cylindrical bale in a bale forming chamber of a baler with wrapping material drawn from its The feed direction of the roll material is applied to the bale with a predetermined stretch of the wrapping material. In particular, but without limitation, the present invention relates to a method and system for circumferentially wrapping a cylindrical shaped baler in a bale forming chamber of a baler with plastic film wrapping material drawn from its reel. A bale whereby the plastic film wrapping material is applied to the bale with a predetermined degree of stretch along the direction of feed of the wrapping material. The invention also relates to a baling machine comprising said system, and the invention also relates to a method for forming and circumferentially wrapping a cylindrical bale. Background technique [0002] Balers for forming cylindrical bales of material ar...
