A system for at least partially grouping a plurality of products, the system comprising: at least one conveyor for conveying the plurality of products downstream in a longitudinal direction in a longitudinally extending first lane so that first, second and third subgroups of products are substantially aligned with one another and arranged in series in the first lane, conveying the second subgroup of products downstream in the longitudinal direction in a second lane, and conveying the third subgroup of products downstream in the longitudinal direction in a third lane; and at least one obstructor mounted for being movable between obstructing and unobstructing positions, wherein in the obstructing position the at least one obstructor arrests downstream travel of the first subgroup of products in the first lane, and in the unobstructing position the at least one obstructor allows downstream travel of the first subgroup of products in the first lane; downstream and upstream pushers each being mounted for being reciprocated back and forth across the first lane in a lateral direction that extends crosswise to the longitudinal direction, the downstream pusher being positioned between the obstructor and the upstream pusher; characterized by at least one control system operatively associated with the downstream and upstream pushers for causing the downstream and upstream pushers to simultaneously move across the first lane in opposite directions from one another for moving the second and third subgroups of products respectively to the second and third lanes (40, 44), wherein the at least one control system comprises an actuator operatively connected to both of the downstream and upstream pushers by way of a linkage including a T-shaped bracket that is centrally pivotably mounted to a frame so that the three arms of the bracket extend outwardly from a central pivot point of the bracket and configured for causing the downstream and upstream pushers to simultaneously move across the first lane respectively in opposite directions for moving the second and third subgroups of products respectively to the second and third lanes (40, 44). at least one conveyor for conveying the plurality of products downstream in a longitudinal direction in a longitudinally extending first lane so that first, second and third subgroups of products are substantially aligned with one another and arranged in series in the first lane, conveying the second subgroup of products downstream in the longitudinal direction in a second lane, and conveying the third subgroup of products downstream in the longitudinal direction in a third lane; and conveying the plurality of products downstream in a longitudinal direction in a longitudinally extending first lane so that first, second and third subgroups of products are substantially aligned with one another and arranged in series in the first lane, conveying the second subgroup of products downstream in the longitudinal direction in a second lane, and conveying the third subgroup of products downstream in the longitudinal direction in a third lane; and at least one obstructor mounted for being movable between obstructing and unobstructing positions, wherein in the obstructing position the at least one obstructor arrests downstream travel of the first subgroup of products in the first lane, and in the unobstructing position the at least one obstructor allows downstream travel of the first subgroup of products in the first lane; in the obstructing position the at least one obstructor arrests downstream travel of the first subgroup of products in the first lane, and in the unobstructing position the at least one obstructor allows downstream travel of the first subgroup of products in the first lane; downstream and upstream pushers each being mounted for being reciprocated back and forth across the first lane in a lateral direction that extends crosswise to the longitudinal direction, the downstream pusher being positioned between the obstructor and the upstream pusher; at least one control system operatively associated with the downstream and upstream pushers for causing the downstream and upstream pushers to simultaneously move across the first lane in opposite directions from one another for moving the second and third subgroups of products respectively to the second and third lanes (40, 44), wherein the at least one control system comprises an actuator operatively connected to both of the downstream and upstream pushers by way of a linkage including a T-shaped bracket that is centrally pivotably mounted to a frame so that the three arms of the bracket extend outwardly from a central pivot point of the bracket and configured for causing the downstream and upstream pushers to simultaneously move across the first lane respectively in opposite directions for moving the second and third subgroups of products respectively to the second and third lanes (40, 44).
