摘要： A shoe press (20) includes: a first member (24); a second member (22); a substantially cylindrical belt; and a processing unit. The first member (24) has a convex pressing surface. The second member (22) includes a shoe (32) with a concave pressing surface (33) substantially complimentary to the convex pressing surface. The second member (22) further includes a pair of substantially circular head plates (34) rotatably mounted on axially opposed ends thereof. The belt (40) is fixed to, extends between, and is rotatable with the head plates (34) such that a portion of the belt (40) passes between the convex pressing surface and the concave pressing surface. The belt includes embedded therein a communications cable (52) having a plurality of sensors (54) configured to generate signals responsive to an operating parameter of the shoe press (20). The processing unit (56) is in communication with the communications cable (52) and processes signals generated by the sensors (54). Thus, signals generated by the sensors (54) and processed by the processing unit (56) represent conditions (particularly pressure, nip width, temperature, strain and stress) within the nip (25) of the shoe press (20) that can be displayed and understood by an operator.

摘要： A system for determining the source of vibration of a nipped roll assembly includes: a first substantially cylindrical roll; a mating structure positioned relative to the first roll to form a nip therewith; a plurality of annular nip condition sensor units mounted on the first roll; each of the annular nip condition sensor units being positioned at different axial locations along the first roll and configured to provide nip condition signals from the nip, the signals indicating a nip condition at multiple circumferential locations; and a processor associated with the sensor units that receives signals from the sensor units. The processor is configured to convert the signals from the sensor units into nip condition readings for the multiple circumferential locations at each axial location. Such a system can detect irregularities in a roll or the mating structure that can cause undesired vibration.

摘要： An industrial roll includes: a substantially cylindrical core and a cover overlying the adhesive layer. The cover comprises a polymeric top stock layer. The top stock layer comprises a mixture of a polymeric material and at least one of a piezochromic material and a thermochromic material. In this configuration, the pressure and/or temperature experienced by the roll cover at any location thereon can be determined visually, without the need for external equipment.

摘要： Covered rolls (10) having reduced residual stresses through the inclusion of one or more intermediate compressive layers (12) and methods for manufacturing are disclosed. In one embodiment, the intermediate compressive layer (12) comprises a three-dimensional fabric that is filled preferably with a thermoset resin system which cures at lower temperature than the cover. In a second embodiment, the precise amount of shrinkage in the roll (10) is predetermined to a high enough degree of accuracy so that a depth for the fabric layer can be used to compensate for the amount of shrinkage, thereby eliminating the need for filling. In a third embodiment, the compressive layer (12) is comprised of a meltable material wherein said material melts at cure temperatures. The resulting cavity is then filled with a thermoset resin. The problems caused by chemical and thermal shrinkage are further reduced through a method based on applying a polymeric cover layer (11) over one or more intermediate compressive layers (12), curing at an elevated temperature, and, allowing the cover (11) to shrink during curing or hardening.

摘要： A system for measuring nip width for a nip present between two rolls includes: (a) a sensor assembly, said sensor assembly including: 1) a first strip formed of a first electrically conductive material having a resistance, the first strip having a first end and a second end and a first measuring zone between the first and second ends; 2) a second strip disposed adjacent the first strip and formed of a second electrically conductive material, the second strip having a second measuring zone disposed adjacent and substantially coextensive with said first measuring zone; 3) a gap defined between the first and second strips and electrically isolating the first and second strips from one another; and 4) wherein at least one of the first and second strips is deformable such that, when the device is placed in the press nip, pressure from the nip rolls forces portions of the first and second measuring zones into electrically conductive contact with one another over a contact length, the contact length corresponding to the nip width. The system further comprises: (b) a resistance-measuring unit that measures an electrical resistance; (c) first and second leads, the first lead being connected to the first strip adjacent the first end, the second lead being connected to the second strip; and (d) a controller operatively associated with the resistance-measuring unit, the controller including computer readable program code, the code including a plurality of data sets, each of the data sets representing a relationship between resistance of a sensor and environmental temperature.
