  • Publication number: 20200101485
    Abstract: A coating apparatus for a moving web that employs a spreader roller in the upweb position in a tensioned-web-over-slot die coater. The spreader roller can help spread webs laterally in a web processing operation, in particular to reduce or remove the presence of wrinkles or bagginess in the web. The spreader roller can be a reverse crown roll that is covered with a resilient material to assist spreading the web to remove wrinkles. The surface curvature of the spreader roller can be formed using layers of material such as a tape, to easily and readily approximate the shape of a reverse crown roll.

  • Patent number: 10029882
    Abstract: The disclosure generally relates to a looped pile film roll core used for winding a polymeric film, a method of winding film on the looped pile film roll core, and a roll of film that includes the looped pile film roll core. The disclosure describes an article and a process to reduce the core impressions created by the starting end of a web on the adjacent web layers next to the core. In one particular embodiment, the present disclosure can lead to a reduction in the amount and severity of such core impressions on a wound polymeric film, by reducing the amount of stress in adjacent layers of wound web.

  • Patent number: 9850082
    Abstract: The provided containers (100, 200) and methods provide for gravitational alignment of a plurality of stacked articles (120), in which at least two edges (140, 142) of each article align along inner walls (108, 114, 208, 214) of a respective container. The aligning walls of the container are provided with low-friction surfaces to facilitate sliding and alignment of the articles. By aligning the stack of articles along two edges, the articles can be registered relative to not only each other but the container itself, thereby facilitating loading, unloading, and conversion of articles in the stack. Optionally, a compressible layer (147) opposing one or both of the aligning walls conforms and distributes stress along the non-aligning edges, thereby preserving registration of the articles relative to each other when the container is transported.
