A round baler comprising: a baling system defining a baling chamber having an access into the baling chamber, wherein the baling system is operable to receive crop material into the baling chamber through the access and form the crop material into a bale within the baling chamber; a wrap system operable to insert a wrap material through the access and into the baling chamber to wrap the bale, the wrap system including: a pair of spool rollers (58, 60) forming a nip therebetween, wherein the pair of spool rollers (58, 60) are configured to rotate about respective axes of rotation (62, 64) in opposite rotational directions relative to each other and receive a wrap material from a supply roll through the nip; a driver coupled to the pair of spool rollers (58, 60) and operable to transmit torque to the pair of spool rollers (58, 60) to rotate the pair of spool rollers (58, 60) about their respective axes of rotation (62, 64); a torque controller coupled to the driver, wherein the torque controller is configured to control torque transmitted to the pair of spool rollers (58, 60) based on a current characteristic of the supply roll related to a current weight of the supply roll of the wrap material to achieve a desired acceleration rate of the spool rollers, such that a leading edge of the wrap material is ejected from the nip at an ejection trajectory that is within an allowable angular range relative to a tangent of the nip, such that the leading edge of the wrap material passes through the access and into the baling chamber. a baling system defining a baling chamber having an access into the baling chamber, wherein the baling system is operable to receive crop material into the baling chamber through the access and form the crop material into a bale within the baling chamber; a wrap system operable to insert a wrap material through the access and into the baling chamber to wrap the bale, the wrap system including: a pair of spool rollers (58, 60) forming a nip therebetween, wherein the pair of spool rollers (58, 60) are configured to rotate about respective axes of rotation (62, 64) in opposite rotational directions relative to each other and receive a wrap material from a supply roll through the nip; a driver coupled to the pair of spool rollers (58, 60) and operable to transmit torque to the pair of spool rollers (58, 60) to rotate the pair of spool rollers (58, 60) about their respective axes of rotation (62, 64); a torque controller coupled to the driver, wherein the torque controller is configured to control torque transmitted to the pair of spool rollers (58, 60) based on a current characteristic of the supply roll related to a current weight of the supply roll of the wrap material to achieve a desired acceleration rate of the spool rollers, such that a leading edge of the wrap material is ejected from the nip at an ejection trajectory that is within an allowable angular range relative to a tangent of the nip, such that the leading edge of the wrap material passes through the access and into the baling chamber. a pair of spool rollers (58, 60) forming a nip therebetween, wherein the pair of spool rollers (58, 60) are configured to rotate about respective axes of rotation (62, 64) in opposite rotational directions relative to each other and receive a wrap material from a supply roll through the nip; a driver coupled to the pair of spool rollers (58, 60) and operable to transmit torque to the pair of spool rollers (58, 60) to rotate the pair of spool rollers (58, 60) about their respective axes of rotation (62, 64); a torque controller coupled to the driver, wherein the torque controller is configured to control torque transmitted to the pair of spool rollers (58, 60) based on a current characteristic of the supply roll related to a current weight of the supply roll of the wrap material to achieve a desired acceleration rate of the spool rollers, such that a leading edge of the wrap material is ejected from the nip at an ejection trajectory that is within an allowable angular range relative to a tangent of the nip, such that the leading edge of the wrap material passes through the access and into the baling chamber.
