Abstract: Methods of separating and positioning discrete articles formed from a continuous length of articles are provided. The methods may comprise the steps of receiving a first portion of the continuous length on a first head in a receiving position of an orbit about a first rotational axis and receiving a second portion of the continuous length on a second head in the receiving position of the orbit about the first rotational axis. The methods may comprise providing a laser system configured to produce and direct a laser beam, and ablating a portion of the continuous length of articles intermediate the first head and the second head with the laser beam to separate the first portion of the continuous length of articles from the second portion of the continuous length of articles, thereby forming a discrete article on the first head.

Abstract: A system for predicting the performance of a rotary unit operation on a web. The system includes a first rotary roll, a second rotary roll, a nip gap between the first rotary unit and the second rotary roll, a web enabled to travel through the nip, a predetermined pattern, and a computing device comprising a processor and a memory component. The first rotary roll and the second rotary roll are enabled to imprint the predetermined pattern on the web.

Abstract: A computer method for simulating motion of at least a portion of a virtual body is disclosed. The method comprises the steps of: providing a surfaced body model; capturing or computing motion data for an external surface of the surfaced body; dividing the body model into at least two volumes, one of the volumes comprising at least a portion of the external surface of the surfaced body and being a deformable volume, and one of the volumes being a prescribed motion volume, the two volumes defining an interfacial surface; moving the external surface of the surfaced body according to the motion data while computing motion of the interfacial surface; and, simulating motion of the portion of a body by driving motion of the interfacial surface through the computed motion to provide an accurately positioned moving deformable surface that can be used in garment design.

Abstract: A method for analyzing the comfort of an actual product on an actual body by use of a virtual product model and virtual body model to calculate a comfort indicator. The method comprises the steps of: (a) providing a virtual body model; (b) providing a virtual product model; (c) providing virtual simulation software; (d) gathering data from actual users of an actual product of a type modeled by the virtual product model; (e) running a virtual simulation for the virtual product model worn on the virtual body model; (f) running a virtual simulation for the virtual body model in the absence of the virtual product model; (g) calculating a difference in deformation on the virtual body model between the virtual simulations; and (h) correlating the calculated difference to the gathered data to determine a magnitude difference, the magnitude difference being the comfort indicator.
