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.

1. A rucker, rerucker, derucker or skin break gripper comprising: a plurality of abutting planar gripper layers, each with a perimeter having a front facing semi-circular side with a plurality of spaced apart arcuate shaped teeth with adjacent teeth separated by a valley of a width narrower than the width of the adjacent teeth, andwherein neighboring gripper layers are arranged so that at least some teeth in a first neighboring gripper layer are misaligned to be offset from underlying or overlying or underlying and overlying teeth in a second neighboring gripper layer. 2. The gripper of claim 1, wherein the plurality of abutting planar gripper layers is a plurality of planar semi-rigid gripper layers stacked together with the teeth facing inward. 3. The gripper of claim 2, wherein the stacked layers are arranged so that teeth and valleys serially repeat over the semi-circular side, and wherein teeth in one layer are misaligned with teeth in at least one abutting layer. 4. The gripper of claim 1, wherein the plurality of abutting planar gripper layers is a set of between 2-10 cooperating stacked planar gripper layers. 5. The gripper of claim 1, wherein the gripper layer has a monolithic polymeric and/or elastomeric body, and wherein the gripper layer is semi-rigid and has a thickness between about 0.125 inches to about 0.5 inches with between about 10-20 teeth. 6. The gripper of claim 1, wherein the teeth have a discontinuous arcuate outer edge. 7. A rucker, rerucker, derucker or skin break gripper comprising: a plurality of abutting planar gripper layers, each with a perimeter having a front facing semi-circular side with a series of spaced apart teeth extending along the perimeter, including intermediate the ends of the semi-circular perimeter;wherein the series of teeth are arcuate in shape to present a series of gripping locations along the perimeter, the teeth spaced apart by valleys, the valleys having a width narrower than the width of the arcuate shaped teeth. 8. The gripper of claim 7, wherein the teeth have a discontinuous arcuate outer edge. 9. A gripper assembly, comprising: a stacked set of cooperating gripper layers having a perimeter with a forward facing semi-circular profile with a series of arcuate shaped teeth facing inward and positioned along the perimeter to present a series of gripping locations along the perimeter wall, including intermediate the ends of the semi-circular perimeter, andwherein each layer is configured so a respective front facing semi-circular profile comprises valleys, with a respective valley separating at least some adjacent teeth, the valley of a width that is narrower than the width of the arcuate shaped teeth. 10. The gripper assembly of claim 9, further comprising a housing holding the stacked set of gripper layers and a bracket attached to the housing configured to attach to an actuation cylinder. 11. The gripper assembly of claim 10, wherein the housing includes at least one laterally extending channel that is configured to cooperate with a rail to allow the gripper assembly to controllably reciprocate in response to actuation of the actuation cylinder. 12. The gripper assembly of claim 9, further comprising a housing holding the stacked set of gripper layers, the housing having a curved forward facing side and a primary surface with a recess having a perimeter shape sized and configured to receive the stacked set of gripper layers. 13.

A gripper assembly, comprising: a stacked set of cooperating gripper layers arranged as a plurality of abutting planar gripper layers each having a perimeter with a forward facing semi-circular profile with a series of arcuate shaped teeth, the arcuate shaped teeth separated by a valley of a width narrower than the width of the teeth; andwherein neighboring gripper layers are arranged so that at least some teeth in a first neighboring gripper layer are misaligned to be offset from teeth in a second neighboring gripper layer so that one row of the layers is configured with teeth and valley in alternating layers. 17. The gripper assembly of claim 16, wherein the teeth have a discontinuous arcuate outer edge. 18. A set of cooperating gripper assemblies, comprising: first and second cooperating gripper assemblies, each gripper assembly comprising a stacked set of cooperating gripper layers having a perimeter with a forward facing semi-circular profile with a plurality of teeth, the first gripper assembly oriented so that the forward facing semi-circular profile faces the second gripper assembly forward facing profile to substantially form a circle when the gripper assemblies are in a closed configuration residing adjacent each other, wherein the first and second cooperating gripper assemblies are configured to close against an outer wall of a horn or chute to contact covering material held thereon;wherein the teeth are arcuate in shape and the teeth are separated from each other along the gripper layer by a valley of a width narrower than the width of the teeth;wherein the semi-circular profile is sized to correspond to a semi-circular outer wall of the chute or horn having a diameter between about 3 inches and about 8 inches; andwherein the stacked set of cooperating gripper layers is arranged as a plurality of abutting planar gripper layers, wherein the stacked layers are arranged so that teeth and valleys serially repeat over the semi-circular profile, and wherein teeth in one layer are misaligned with teeth in at least one abutting layer. 19. An apparatus for rucking, derucking, rerucking and/or braking covering material from or onto a chute body, comprising: a frame;a gripper assembly comprising first and second cooperating gripper subassemblies each having a perimeter with one side having a semi-circular shape, wherein the side having the semi-circular shape comprises a set of stacked planar gripper layers, at least some of the layers having a series of spaced apart arcuately-shaped teeth spaced along the perimeter to provide a series of locations for gripping the covering materials, including intermediate the ends of the semi-circular perimeter, the arcuately-shaped teeth separated by a valley that is narrower than the width of the arcuately-shaped teeth; andat least one actuator attached to the gripper assembly and in communication with a controller, wherein the first and second gripper assemblies have an automated stroke cycle whereby each is configured to travel inwardly a distance sufficient to snugly abut an outer surface of a chute or horn body and remain in contact with the chute or horn body to pull covering material or brake the covering material. 20. The apparatus of claim 19, wherein the first and second gripper subassemblies each include a respective a housing that includes at least one laterally extending channel that is configured to cooperate with a rail to allow the respective gripper subassembly to controllably reciprocate in response to actuation of the actuator, and wherein the housing has a curved forward facing side and a primary surface with a recess having a perimeter shape sized and configured to receive the stacked set of gripper layers.
