Regarding claim 21, Merritt anticipates the transmission unit as recited in claim 19 as explained above. Merritt further discloses the press roller driven part is configured to at least indirectly drive the pressing roller in a feed area of the pressing chamber (drive shaft 50 has a driving part which drives starter pressing roller 26 in Fig. 1 in the feed area of pressing chamber 22), and the press belt driven part is configured to at least indirectly drive a pressing belt which is configured to be driven circumferentially (the Press Belt Driven Part as annotated above is configured to drive pressing belt apron 24 circumferentially). Regarding claim 23, Merritt anticipates the transmission unit as recited in claim 17 as explained above. Merritt further discloses the cutting rotor driven part further comprises a cutting rotor gearwheel which is configured to non-rotatably connect to the cutting rotor (cutting rotor gearwheel 210 in Fig. 8 is fixed to rotate with rotor drive shaft 220 which has rotor 18 mounted thereon; col. 8, line 14-27) and to interact, either directly or indirectly, via at least one intermediate gearwheel (intermediate transmission gearwheel 200 in Figs. 2-3 and 8), with the second coupling gearwheel (member 59 in Figs. 6 and 7). Regarding claim 24, Merritt anticipates the transmission unit as recited in claim 16 as explained above. Merritt further discloses a coupling spring element which is configured to preload the first coupling gearwheel in a direction of the coupling position (Figs. 6 and 7 show a coupling spring element which is configured to preload gearwheel member 60 in the direction of the coupling position shown in Fig. 6). Regarding claim 25, Merritt anticipates the transmission unit as recited in claim 16 as explained above. Merritt further discloses a switch mechanism which comprises at least one shift element (switch mechanism assembly 56 in Figs. 2-5 moves shift element link member 64; col. 7, line 31-43), wherein, the at least one shift element is configured to be adjustable between a passive position (shown in Figs. 3 and 5) and an active position (shown in Figs. 2 and 4) and, when the at least one shift element is adjusted to the active position, to engage axially laterally on the first coupling gearwheel so as to adjust the first coupling gearwheel to the release position (shift element 64 moves member 60 axially laterally from the active position shown in Figs. 2 and 4 to the passive position shown in Figs. 3 and 5 by disengaging teeth 72 and 74 and shown in Figs. 6 and 7). Regarding claim 26, Merritt anticipates the transmission unit as recited in claim 25 as explained above. Merritt further discloses the at least one shift element (shift element link member 64 in Figs. 2-5) is adjustable between the active position and the passive position by pivoting about a shift element pivot axis (see “Pivot Axis” annotation to Fig. 4 of Merritt reproduced below) so as to engage with at least one shift section (shift section 60 in Figs. 2-5) which is spaced from the shift element pivot axis on the first coupling gearwheel (gearwheel member 60 in Figs. 6 and 7). PNG media_image2.png 1264 849 media_image2.png Greyscale Regarding claim 27, Merritt anticipates the transmission unit as recited in claim 26 as explained above.

Regarding claim 28, Merritt anticipates the transmission unit as recited in claim 27 as explained above. Merritt further discloses the actuating element (arm 70 in Figs. 2-5) is pivotable about an actuating element pivot axis (arm 70 pivots about gear support shaft 80 in Figs. 2-5) and comprises an eccentric section (see “Eccentric Section” annotation to Fig. 4 below) which is configured to interact with an actuating section (see “Actuating Section” annotation) of the at least one shifting element, and the actuating section is spaced apart from the shifting element pivot axis and from the at least one shifting section (the Actuating Section is spaced apart from the annotated Pivot and from shifting section 60). PNG media_image3.png 1264 1095 media_image3.png Greyscale Regarding claim 29, Merritt anticipates the transmission unit as recited in claim 27 as explained above. Merritt further discloses the actuating element further comprise a drive profile (see “Drive Profile” annotation to Fig. 2 of Merritt reproduced below) which is arranged outside a transmission housing for a positive engagement with a tool (the Drive Profile is arranged outside transmission housing 40 in Fig. 2). PNG media_image4.png 1248 782 media_image4.png Greyscale Regarding claim 30, Merritt discloses a round baler comprising: a frame (Frame 11 in Fig. 1; col. 5, line 27); a press element which is configured to be driven relative to the frame and to act on a harvested material in a pressing chamber (press element apron 24 in Fig. 1; col. 5, line 43); a cutting rotor which is configured to be driven relative to the frame and to convey the harvested material towards the pressing chamber (cutting conveying rotor 18 in Fig. 1; col. 6, line 7-11); and the transmission unit as recited in claim 16 (see explanation of rejection of claim 16 above), wherein, the press roller driven part is coupled at least indirectly driving to the press element (starter pressing roller 26 in Fig. 1 at least indirectly drives press element apron 24 through belt 53; col. 6, line 45-55), and the cutting rotor driven part is coupled at least indirectly driving to the cutting rotor (cutting rotor driven part drive wheel 54 in Figs. 2-7 drives cutting conveying rotor 18 in Fig. 1). Allowable Subject Matter Claim 22 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: Claim 22 claims the press roller driven part has a press roll gearwheel connected to the pressing roller. Merritt appears to be the closest prior art. Merritt’s interpreted pressing roller 26 in Fig. 1 is shown to be drivingly mounted on drive shaft 50 which has been interpreted as being the transmission drive shaft of claim 16. Therefore, Merritt does not disclose a gearwheel and intermediate gearwheel as claimed.
