Provided is a printer that can appropriately handle a paper (media) wound into a roll with one end of the paper affixed to a core, when the trailing end of the paper is detected, the trailing end of the paper being attached to the winding core in multiple ways. The printer has: a roll paper support that supports the core of a roll of paper; a roll driver that turns the core and delivers the paper; a conveyance device that conveys the delivered paper; a tension detection switch that outputs a first detection value when tension produced on the paper delivered from the roll is greater than or equal to a threshold; and a controller that drives the roll driver in the direction delivering the paper when the output of the tension detection switch changes to the first detection value in response to rotation of the core.

METHODS FOR MANUFACTURING PRINTED LAMINATES
20190276260 · 2019-09-12 ·

Methods for manufacturing printed laminates or elastic printed laminates are disclosed. The printed laminates may have a first extensible material and a second extensible material. The first extensible material may have a plurality of repeating graphic sets each having a repeating graphic set length. The first extensible material may have a first strain and the second extensible material may have a second, different strain. The second strain may be constant. The first strain may be variable to correspond to the repeating graphic set lengths to a predetermined laminate pitch. The first and second extensible material may be joined together at a point of joinder. An elastic member, such as a plurality of elastic strands, for example, may be positioned intermediate the first and second extensible materials to form an elastic laminate.

Tensioning mechanism for a textile feed to a stepped operation digital textile printer
10407267 · 2019-09-10 · ·

A textile feed for a stepped operation digital textile printer, comprises a textile feeding mechanism, and a tension storage mechanism. The textile feeding mechanism feeds the textile in a forward direction onto the printer, but is at the same time mechanically connected to a tension storage mechanism which is tensioned by the forward feeding. At the end of the feed step, the tension storage mechanism releases respectively stored tension to cause the feed mechanism to briefly reverse feed, thereby to pull the textile taut and take up any slack caused by the feeding step. The textile is thus kept taut, to allow effective digital printing by the printer.

Rolled material tensioning and loading system
10399809 · 2019-09-03 · ·

Maintaining a level of tension on material as it is processed in a manufacturing operation assists in the processing of the material. The tension of the material as it is fed through a process station is maintained by a material sag portion, such as an unsupported portion of the material extending between a roll of the material and the process station. The formation of the sag portion and the loading of the material forming the sag portion are automated and adjusted with a system having a material storage retrieval system, a shuttle, a tensioning device, and/or a processing station.
