摘要： A pre-stretched film roll of a mono orientated linear low density polyethylene (LLDPE) is stretched between 30% and 320% depending on the final product that is required. Stretching is in the machine direction (MD) at a controlled rate in two stages. Differentially rewinding the film entraps air between the layers of the roll and creates soft overlapping edges around the roll to produce a spongy, “soft” roll that prevents and resists drop damage due to its shock absorbent characteristic.

摘要： A grapple for use in an overshot has a tension ring with a reduced helix diameter. However, the helix diameter is not reduced on either sides of the control finger slot to allow the grapple to remain in contact with the control. In the alternative, a composite helix member may be utilized. Another embodiment comprises the inclusion of expansion blades on the inner diameter (“ID”) of the tension ring which allow the grapple to expand substantially before the fish reaches the segments. Another embodiment provides for a control with an offset finger to allow the guide thread ID to be smaller than the bowl helix major ID. Yet another embodiment provides a spiral grapple having grooves along its axis to provide the ability to catch a larger range of fish.
摘要翻译： 用于过冲的抓斗具有螺旋直径减小的张力环。 然而，螺旋直径在控制指槽的任一侧不减小，以允许抓斗保持与控制接触。 在替代方案中，可以使用复合螺旋构件。 另一个实施例包括在张力环的内径（“ID”）上包括膨胀叶片，其允许抓钩在鱼到达节段之前基本上膨胀。 另一实施例提供了具有偏移手指的控制以允许引导线ID小于碗螺旋主要ID。 另一个实施例提供一种具有沿其轴线的凹槽的螺旋抓钩，以提供捕获较大范围的鱼的能力。
