Abstract
A round baler comprising a baling chamber mounted on a main frame for forming cylindrical packages of crop material therein, the baling chamber being at least partially defined by a pair of side walls and an apron assembly having an inner run which is guided at the inside of a cylindrically shaped continuous wall, and an outer run which is guided at the outside of said continuous wall. The continuous wall is provided with an opening for the recuperation into the chamber of crop material which has been entrained by the apron assembly when the latter left the baling chamber and entered its outer run.
Claims13
A baler for forming crop material into cylindrical bales, said baler comprising:
- a. a main frame further comprising a pair of side walls;
- b. a baling chamber extending between said side walls for forming cylindrical packages of crop material therein;
- c. means attached to said main frame for picking up crop material from a field, while said frame is travelled thereover, and conveying said material towards said baling chamber;
- d. wrapping means installed adjacent said baling chamber for applying wrapping material to the periphery of a completed cylindrical package, said wrapping means further comprising:
- i. a net supply means further comprising a transverse support shaft mounted for rotation between said side walls and means for securing thereto a supply roll of said wrapping material;
- ii. a dispensing mechanism for receiving wrapping material from said supply roll and dispensing it to the periphery of said completed cylindrical package;
- iii. a severing means for severing said wrapping material after an amount thereof has been dispensed about the periphery of said cylindrical package;
- and
- iv. a drag control means comprising means for maintaining the wrapping material stretched while it is being unwound from said supply roll;
- f. said drag control means further comprises a friction disc affixed to said support shaft and rotated therewith and a brake shoe engages the periphery of said friction disc;
- and
- g. means for varying the force by which said brake shoe is loaded against said friction disc in accordance with the actual amount of wrapping material remaining on said supply roll, wherein said varying means varies said force in accordance with the actual diameter of said supply roll.
