摘要：

An elastic material is cut, set to a product pitch, stretched a desired amount and applied to a moving target web to create a product with a desired amount of elasticity over a desired area. A vacuum wheel with an aggressive vacuum pattern is used for securing and stretching the stretchable film, the same type of wheel also capable of being used as a trim removal device.
