conveying path, product carriers which are movable along the guide. ## Claims ### Claim 1 A device for changing the orientation of slaughter products such as slaughter birds, comprising an endless guide extending along a conveying path, product carriers which are movable along the guide and which are interconnected at regular intervals by an endless flexible conveying element, which product carriers each comprise a base part and a rotary part connected to the base part, wherein the base part is provided with at least one runner which cooperates with the guide during operation of the device, and wherein the rotary part is provided with an engagement part and with a suspension part connected to the engagement part for suspending a slaughter product from the suspension part, which rotary part is rotatable about an axis of rotation that extends in a vertical plane perpendicular to the conveying path, wherein the device further comprises at least one operating element disposed beside the conveying path, which is configured to cooperate with the engagement part for causing the rotary part to rotate about the axis relative to the base part, wherein the conveying path comprises an arcuate section extending in a vertical plane, wherein the product carriers are present on the outer side of the arc, and that the operating element is disposed beside the arcuate section for causing the rotary parts of the product carriers to rotate at least in part about the associated axes of rotation during passage of the product carrier through the arcuate section, wherein the rotary part cannot pivot about a horizontal pivot axis that extends perpendicular to a vertical plane parallel to the arcuate section during passage of the associated product carrier through the arcuate section. ### Claim 2 (depends on 1) A device according to claim 1, wherein the engagement part comprises a contact body which is in contact with the operating part via a contact surface during cooperating contact between the engagement part and the operating element, wherein the contact surface is at least in part arcuate in shape, defining an arc which is oriented perpendicular to the axis of rotation and wherein the axis of rotation is located on the inner side of the arcuate shape, wherein the axis of rotation intersects the arc at the location of a point of intersection, wherein the distance between a point on the arc and the point of intersection is different for different points along the arc. ### Claim 3 (depends on 2) A device according to claim 2, wherein the shape of the contact body conforms at least in part to the shape of an oval. ### Claim 4 (depends on 1) A device according to claim 1, wherein the operating element and the respective engagement parts are configured to cooperate such that the rotation of the rotary part about the axis of rotation relative to the base part takes place during movement of the product carriers over a distance greater than the distance apart between the product carriers. ### Claim 5 (depends on 1) A device according to claim 1, wherein the product carriers each comprise operable locking means for locking the rotary part against rotation about the axis of rotation in a first operating position of the locking means and for enabling the rotary part to rotate about the axis of rotation in a second operating position of the locking means. ### Claim 6 (depends on 1) A device according to claim 1, wherein the base part comprises two pairs of runners arranged one behind the other. ### Claim 7 (depends on 1) A device according to claim 1, wherein the device comprises a weighing station downstream of the arcuate section for weighing poultry that has been moved through the arcuate section. ### Claim 8 (depends on 7) A device according to claim 7, wherein the weighing station comprises a weighbridge that forms part of the guide. ### Claim 9 (depends on 1) A device according to claim 1, wherein the operating element and the respective engagement parts are configured for rotating the rotary part through at least 30 degrees relative to the base part. ### Claim 10 (depends on 9) A device according to claim 9, wherein the operating element and the respective engagement parts are configured for rotating the rotary part through at least 60 degrees relative to the base part. ### Claim 11 (depends on 1) A device according to claim 1, wherein the base part and the rotary part are rigidly interconnected except for the fact that the rotary part can rotate about an axis of rotation relative to the base part. ### Claim 12 (depends on 1) A method for using a device according to claim 1, wherein the rotary parts of the product carrier rotate at least in part about the associated axes of rotation during passage of the product carrier through the arcuate section. ### Claim 13 A device for changing the orientation of slaughter products such as slaughter birds, comprising an endless guide extending along a conveying path, product carriers which are movable along the guide and which are interconnected at regular intervals by an endless flexible conveying element, which product carriers each comprise a base part and a rotary part connected to the base part, wherein the base part is provided with at least one runner which cooperates with the guide during operation of the device, and wherein the rotary part is provided with an engagement part and with a suspension part connected to the engagement part for suspending a slaughter product from the suspension part, which rotary part is rotatable about an axis of rotation that extends in a vertical plane perpendicular to the conveying path, wherein the device further comprises at least one operating element disposed beside the conveying path, which is configured to cooperate with the engagement part for causing the rotary parts to rotate about the axis relative to the base part, wherein the engagement part comprises a contact body which is in contact with the operating part via a contact surface during cooperating contact between the engagement part and the operating element, wherein the contact surface is at least in part arcuate in shape, defining an arc which is oriented perpendicular to the axis of rotation, and wherein the axis of rotation is located on the inner side of the arcuate shape, wherein the axis of rotation intersects the arc at the location of a point of intersection, wherein the distance between a point on the arc and the point of intersection is different for different points along the arc.
