Abstract
Methods, apparatus and associated devices for one or more of rucking, derucking, braking or rerucking sleeves of covering material off of and/or onto a chute body include a gripper with a stacked set of discrete gripper layers with forward facing protrusions. The grippers can have an automated stroke cycle whereby cooperating pairs of gripper assemblies can be configured to travel inwardly a distance sufficient to snugly abut an outer surface of a chute body and remain in contact with the chute body while traveling in a longitudinal and/or axial direction to contact covering and pull the covering along the chute body.
