During the process of making elastomeric laminates, elastic material is advanced and stretched in a machine direction and may be joined with one or more substrates advancing in the machine direction. During the assembly process, one-way snare apparatuses and methods may be configured to automatically isolate elastic materials that may break. The one-way snares may include a housing and a snare member movably connected with the housing, wherein the snare member is movable relative to the housing between a first position and a second position. The one-way snares are adapted to permit advancement of continuous elastic strands in a first direction through the housing when the snare members are in the first position, and to prevent an end portion a broken elastic strand from retracting in a second direction through the housing when the snare member is in the second position, wherein the second direction is opposite the first direction. |

1. A one way snare apparatus for isolating a broken elastic strand, the apparatus comprising:
a housing, the housing comprising:
a first side wall comprising a first slot, the first slot including a first end portion and an opposing second end portion;a second side wall separated from the second side wall along a cross direction, the second side wall comprising a second slot, the second slot including a first end portion and an opposing second end portion anda cross member connected with and separating the first side wall and the second side wall, the cross member defining an outer circumferential surface; a snare member connected with the housing, wherein the snare member is movable relative to the housing between a first position and a second position, wherein the snare member is movable in a first direction from the second position to the first position, and wherein the snare member is movable in a second direction from the first position to the second position; wherein when the snare member is in the first position, the snare member permits advancement of a continuous elastic strand in the first direction; and wherein when the snare member is in the second position, the snare member prevents an end portion of a broken elastic strand from retracting in the second direction through the housing, wherein the second direction is opposite the first direction; and wherein the snare member comprises a roller defining an outer circumferential surface, the roller comprising:
a first end portion movably connected with the first slot;a second portion movably connected with the second slot; and wherein the snare member is placed in the first position when the first end portion of the roller is moved toward the first end portion of the first slot, and when the second end portion of the roller is moved toward the first end portion of the second slot; and wherein when the snare member is placed in the second position when the first end portion of the roller is moved toward the second end portion of the first slot, and when the second end portion of the roller is moved toward the second end portion of the second slot; wherein the housing further comprises a bottom wall; wherein the outer circumferential surface of the roller is rollingly connected with the bottom wall; and wherein the outer circumferential surface of the roller comprises teeth, and wherein the bottom wall comprises teeth adapted to mesh with the teeth of the roller. |
