CROSS WEB TENSION MEASUREMENT AND CONTROL
The present disclosure generally relates to systems and methods for transporting a web through a web processing apparatus. In one aspect, a web tension adjustment unit for guiding a web. The web tension adjustment unit includes a first guide roller. The first guide roller includes an adjustment unit. The web tension adjustment unit further includes one or more first non-contact sensors positioned to measure displacement data of the web at a first location. The web tension adjustment unit further includes a system controller for controlling the adjustment unit based on the measured displacement data.
Adaptive sheet caliper control system and apparatus and methods
The present invention provides an adaptive control system to control a plant using direct output feedback in which a function of the full plant state, as opposed to estimates thereof, is used for feedback control of the plant. The adaptive control system of this invention is therefore highly useful in the control of plants, particularly plants for controlling the physical properties of rolls of web material and more particularly a calendering apparatus. Accordingly, in a particularly preferred embodiment the adaptive control system of this invention controls loading of a calender apparatus, such as a pair of opposed rolls forming a calendering stack, based upon the physical properties of a previously processed web.
SMARCA INHIBITORS AND USES THEREOF
The present invention provides compounds, pharmaceutically acceptable compositions thereof, and methods of using the same for the modulation of one or more SWI/SNF-related matrix associated actin dependent regulator of chromatin subfamily A (SMARCA) and/or polybromo-1 (PB-1) protein via ubiqitination and/or degradation by compounds. The compounds are useful in treatment of cancer.
Flexible drive and core engagement members for a rewinding machine
A core end engagement assembly is provided for a rewinding machine. The core end engagement assembly is configured to engage an end of the core and transmit rotational movement to the core during winding of the web material about the core. The assembly may include a drive housing. A chuck may project from a first end of the drive housing and may be configured to engage the end of the core. A first actuator may reciprocate the drive housing along a central axis of the core between an engagement and disengagement position of the chuck relative to the core. A second actuator may be mounted on the drive housing. The second actuator may be configured and adapted to move the chuck between release and hold positions. A flexible drive shaft operatively connects with and rotationally drives the chuck.

Sleeve, Winding Device, and Method for Repeated, Successive Winding of Webs to Form Reels of Material
The invention describes a sleeve for sliding onto and removing from a winding shaft, which comprises a one-piece workpiece defining a cylinder, which workpiece comprises two edge regions each having an edge, the edge regions overlapping one another, the sleeve having a first diameter in a relaxed state, the sleeve in a clamped state having a second diameter which is different from the first diameter, the sleeve in the clamped state experiencing an elastic deformation as compared to the relaxed state.
DRYING DEVICE AND LIQUID DISCHARGE APPARATUS INCORPORATING SAME
A drying device includes a drum, a contact conveyance roller, and a cooling device. The drum heats a continuous medium while conveying the continuous medium. The continuous medium is wound around a circumferential surface of the drum. The contact conveyance roller contacts the drum at a downstream end of a portion of the continuous medium wound around the circumferential surface of the drum in a conveyance direction of the continuous medium. Further, the contact conveyance roller conveys the continuous medium separated from the drum. The continuous medium is wound around the contact conveyance roller. The cooling device cools the contact conveyance roller.
