Abstract: An agricultural baler. The agricultural baler includes a baling chamber including a first segment, a plunger, and a baling chamber. The agricultural baler further includes a controller and a pre-compression chamber configured for gathering crop material, periodically forming a slice of the crop material, and pushing the slice towards the baling chamber into the first segment of the baling chamber. The agricultural baler further includes a slice-presence-detecting sensor disposed in an upper region of the first segment of the baling chamber, the slice-presence-detecting sensor comprising an output operationally connected to the controller. The plunger is configured for reciprocally moving in the baling chamber to compress slices of crop material into a bale. The controller is configured for adjusting a synchronization between the periodically forming and pushing of the slice in the pre-compression chamber and the reciprocally moving of the plunger.

Abstract: An agricultural baler system includes a bale chamber, a compressing device and at least one sensor. The compressing device is coupled to the bale chamber and periodically compresses gathered crop material in the bale chamber. The sensor is coupled to the bale chamber and it produces a signal. The signal contains information that includes the load on at least one of the compressing device and the density of the forming bale.

Abstract: Stationary plates are mounted in the spaces between the segments of a roll. At least one of the plates comprises a cam-like extension, protruding from the roll surface for preventing wrapping material from wrapping around the roll.

Abstract: A baler and a method of using the baler to produce high density bales based on arrangement and control of compression rollers. The baler comprises a pick-up assembly configured to pick-up crop material; a rotary feeder; a compression assembly comprising at least one compression roller configured to generate a pressure on the crop material as it passes between the compression roller and another compression component in the baler; and a bale chamber, wherein the pre-compressed crop forms a bale. The compression roller and compression component define an adjustable gap therebetween. The one or more compression rollers and/or baler compression components may be located in various locations in the baler. By adjusting the gap, pressure exerted on the crop material as it passes between the compression rollers and baler compression components may be controlled, resulting in bales of higher density.

Abstract: A device is disclosed for introducing the free end of a wrapping material into the bale forming chamber of a round baler. The device comprises a pair of elongate plates 122a and 122b that are biased towards one another to grip the wrapping material between them. One of the plates 122a has a leading edge that projects further than the other in the feeding direction of the wrapping material 30. In the invention, the leading edge is formed with forward projecting resiliently flexible fingers 124d which are transversely spaced from one another.

Abstract: A round baler comprises a mechanism for encircling a bale after it has been formed with a wrapping material drawn from a web on a supply roll. In the invention, means are provided for adjusting the width of the web of wrapping material as it is offered to a formed bale, so as to selectively enable and disable the wrapping of the edges of the bale.

Abstract: A tying mechanism for a baler, operable to produce two successive knots in a pair of strands during one full operating cycle of the tying mechanism; the mechanism comprising a twine holder for maintaining the pair of strands in a suitable position throughout the complete formation of a first one of said two successive knots and to continue to maintain the pair of strands in a suitable position during the initial stage of the formation of a second one of said successive knots, and a cutter co-operating with the twine holder for severing the strands during formation of said first one of said two successive knots. The tying mechanism further comprises releasing means to release said pair of strands from the twine holder before full completion of said second one of said two successive knots. No twine tails will be formed, preventing knotter problems occurring during the baling process. Also environmental pollution will be prevented since no twine tails will be removed from the baler.
