MONITORING APPLICATOR RODS
20170275824 · 2017-09-28 · ·

A sensor signal is generated from a plurality of sensors located on a sensing roll, wherein each signal is generated when each sensor enters a first nip between the sensing roll and a rotating component during each rotation of the sensing roll. A rotating applicator rod forms forming a second nip with the sensing roll such that each sensor enters the second nip during each rotation of the sensing roll. A periodically occurring starting reference is generated associated with each rotation of the applicator rod and the signal generated by each sensor is received so that a particular one of the sensors which generated the signal is determined and one of a plurality of tracking segments is identified. The signal is stored to associate the sensor signal with the identified one tracking segment.

OFFLINE ROLL TO ROLL WEB COATING
20250163649 · 2025-05-22 ·

A coating system for coating a web of paper includes spaced apart support rollers, a guide roller, a tension roller, a motor, a dispenser, and a control system. The support rollers support respective spools of paper. The guide roller is configured for guiding the paper along a path between the spools of paper. The tension roller is positioned along the path and is configured to engage the paper. The motor is operable to rotate the support rollers and/or the tension roller. The dispenser is fixed proximal to the path and is operable to guide liquid coating onto the paper located on the path. The control system is in communication with the motor and is configured to direct the motor to cause the paper to shift in either direction along the path between the spools.

IN-LINE APPLICATION OF DISPERSION BARRIER
20250163648 · 2025-05-22 ·

A coating and pressware forming system comprising a coating system and a pressware forming system in-line with the coating system. The coating system includes a supply roll carrier and rollers configured for guiding and unwinding the paperboard material from a spool such that the paper traverses a path to the pressware forming system. The coating system also includes a waterfall dispenser fixed above the path the paper traverses for evenly applying liquid coating to the paperboard material. The waterfall dispenser includes a pressure chamber fluidly coupled with the source of liquid coating and having a gap through which the liquid coating is forced to flow evenly across a width of the paperboard material. The coating system may also include air nozzles for drying the coating on the paperboard material. Following this drying, the coating system may guide the coated paperboard material directly to the pressware forming system.
