Abstract: Apparatus and methods for impinging a heated fluid onto the surface of a substrate and then locally removing the impinged fluid. The apparatus and methods may be used to heat a surface of a substrate e.g. so that the substrate can be melt-bonded to another substrate.

Abstract: A method of making a mechanical fastening strip and a reticulated mechanical fastening strip are disclosed. The method includes providing a backing having upstanding posts; providing interrupted slits through the backing, the interrupted slits being interrupted by at least one intact bridging region; spreading the slit backing to provide multiple strands separated from each other between at least some of the bridging regions to provide at least one opening; and fixing the multiple strands of the backing in a spread configuration. The reticulated mechanical fastening strip includes multiple strands of a backing attached to each other at bridging regions in the backing and separated from each other between the bridging regions to provide openings. Upstanding posts on each of the multiple strands have bases attached to the backing, and each of the multiple strands has a width that is greater than that of the bases of its attached upstanding posts.

Abstract: A method of controlling a slot die comprises, while continuing to pass the extrudate through the fluid flow path and out the applicator slot, changing the position of the actuators with the controller to either increase the cross-directional thickness of the fluid flow path adjacent each of the actuators or substantially close the fluid flow path adjacent the actuators, and after changing the cross-directional thickness of the fluid flow path adjacent each of the actuators, while continuing to pass the extrudate through the fluid flow path and out the applicator slot, repositioning each of the actuators with the controller according to the set of discrete settings to resume operating the slot die with the actuators positioned according to the set of discrete settings.

Abstract translation: 一种控制狭槽模头的方法包括：在连续地将挤出物通过流体流动路径并从施加器槽中通过的同时，改变致动器与控制器的位置，以增加流体流动路径的横向厚度 或者基本上关闭与致动器相邻的流体流动路径，并且在改变与每个致动器相邻的流体流动路径的横向厚度的同时，继续使挤出物通过流体流动路径并且从施加器狭槽出来， 根据一组离散设置，使用控制器重新定位每个致动器，以根据一组离散设置使致动器定位，以恢复操作槽模。

Abstract: A method of separating strands of a slit web is disclosed. The method includes providing a slit web having a length in a machine direction and running the slit web in the machine direction onto a stretchable surface. The slit web includes multiple strands provided by a plurality of slits extending in a first direction not parallel to a cross-machine direction. The slit web is in contact with the stretchable surface for a path length in the machine direction, and for at least a portion of the path length, the stretchable surface is stretching in the cross-machine direction. The traction between the slit web and the stretchable surface during the stretching at least partially separates at least some of the multiple strands of the slit web in a second direction transverse to the first direction. A method of increasing a width of a polymeric netting is also disclosed.

Abstract translation: 公开了一种分离狭缝网的股线的方法。 该方法包括提供在机器方向上具有长度的狭缝网，并且将缝线沿机器方向运行到可拉伸表面上。 狭缝网包括由沿不平行于跨机器方向的第一方向延伸的多个狭缝提供的多股线。 狭缝网与机械方向上的路径长度的伸缩面接触，并且对于路径长度的至少一部分，伸缩面在横向上进行拉伸。 在拉伸过程中，狭缝腹板和可拉伸表面之间的牵引力至少部分地在横向于第一方向的第二方向上分开狭缝腹板的多个股线中的至少一些。 还公开了增加聚合物网的宽度的方法。
