A control system is provided for a converting line. The converting line has an unwinder for unwinding web material from a roll of web material and at least one independently driven roll for directing the web material unwound from the unwinder to the converting line. The control system has a controller and a tension sensor configured to be arranged downstream of the at least one driven roll. The tension sensor is configured to sense a tension in the web as the web is passed downstream of the driven roll, generate a signal indicative of sensed web tension, and transmit the signal of sensed web tension to the controller. The controller is configured to a generate and transmit to the unwinder a signal to change the speed of the unwinder based upon the tension sensed by the tension sensor.

An apparatus for the preparation of comestible-containing sandwich products comprises a sandwich product assembly station and corresponding means for the fabrication and assembly of a sandwich product in the vertical direction. The apparatus includes an extruder nozzle, wafer trays and corresponding components for the location of wafers on opposite sides of the extruded product, an indexing wheel for receiving the assembled sandwich product, and sandwich transporting means for moving the sandwich to a wrapping assembly and from there to a discharge end, wherein all of the components of the apparatus are mounted in cantilevered fashion on a vertical support or base member. Each element is powered individually by a servo motor or actuator and controlled by a controller allowing the variability of throughput for each station.

An apparatus and method of automatically moving yarn packages between yarn processing stations in a textile environment that includes the steps of providing a yarn package elevator, transporting a yarn package on the yarn package elevator from a textile machine position to a common transfer location, and holding the package in a stationary position on an elevator tray. A label is applied to a surface of the package and the elevator tray and package is moved to a knot-tying location, the package is removed from the elevator tray to a knotting head apparatus at the knot-tying location and a knot is tied in a package yarn tail of the package to secure the package tail from unraveling in subsequent package handling steps. Correct application of the knot to the yarn tail is either validated, or in the alternative, if the knot is not validated, the package is forwarded to a location for manual reworking to apply a correct knot to the yarn tail.

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.

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.

A device for introducing patterns by radiating a wound continuous substrate. The device provides patterning during continuous roll-to-roll movement without material slippage and with minimal distortion by providing a dancer roll between a processing drum and an unwinder roll on one side, and a winder roll on the other side, for tautly guiding the continuous substrate along a contact surface of at least half of the circumference of the processing drum in order to drive the continuous substrate without slippage. The dancer rolls are adapted to tautly guide the advancing substrate web and returning substrate web with a constant force, and an equilibrium is adjustable between a defined counterforce and the constant action of force on the dancer roll by a stabilization device, and is maintained constant by a controller based on measured deflections of the dancer roll by controlling the rotational speed of the unwinder and winder rolls.

An image forming apparatus includes a sheet cassette, a sheet conveying portion, an image forming portion, a position detecting portion, and an image position correcting portion. The sheet conveying portion conveys a sheet from the sheet cassette attached to the apparatus main body, along a sheet conveyance path whose width direction matches the main direction. The position detecting portion detects a position of a detection-target portion that is a part of the sheet cassette, in the main direction based on the apparatus main body. The image position correcting portion corrects an image formation position in the main direction at which the image is formed by the image forming portion, based on the position detected by the position detecting portion.

A control system for a converting line has a sensor configured to sense a distance between the sensor and a surface of a roll of web material as the roll of web material is unwound from an unwinder and directed to the converting line. The controller is configured to: (i) determine a diameter measurement of the roll as the roll rotates based upon the sensor signals; (ii) store a plurality of data structures in a memory of a controller of a control system wherein the data structures comprise a plurality of data items associated together as the diameter measurements of the roll of the web material; (iii) process by a statistical regression analysis the data structures associated with the diameter; and (iv) generate signals for controlling the converting line based upon the processed diameter measurements.

Apparatus and methods for web tension control are provided. In an example, an apparatus can include a tension beam configured to deflect in a predictive manner when under a force load, a first shaft directly coupled to the tension beam and configured to mechanically interface with a torque device, a second shaft directly coupled to the tension beam opposite the first shaft and configured to interface with a structural member of a web machine, and a strain gauge coupled to the tension beam and configured to provide an electrical representation of the force load.
