摘要:
It has now been determined that a first coating layer may be applied to a substrate by a first coating die in a much thinner layer than its rheological properties and/or surface properties would normally allow. This is accomplished by using a second coating fluid dispensed from a second coating die acting as a “dynamic liquid squeegee” to transport, spread, even, or meter the first coating layer on the substrate by varying a gap between the second coating die and the substrate.

The present method comprises providing a flexible web substrate (e.g., polymeric flexible web substrates) that forms at least part of a component of a device, coating so as to wet-out on and cover all or a substantial portion of a major surface on one side or both sides of the flexible web substrate with flowable polymeric material, while the flexible web substrate is moving in a down-web direction, and solidifying the polymeric material so as to form one cleaning layer on the major surface of one side or both sides of the flexible web substrate. The present invention can be utilized in a continuous in-line manufacturing process. In applications of the present invention where the flexible web substrate will not form a component of a device, the present invention broadly provides a method for cleaning particles from a flexible web of indefinite length. Each cleaning layer forms a substantially adhesive bond to the major surface that is readily removable without damaging or leaving a substantial residue of cleaning layer material on the major surface. A substantial number of the particles that were on this major surface are captured by and removable with the cleaning layer.

The invention is embodied in a commercial foodservice system having a primary counter unit constructed and arranged to perform a direct or related foodservice function, and an independent peripheral unit constructed and arranged in juxtaposition with the counter unit to perform a non-foodservice function. The foodservice system encompasses arrangements of multiple counter units disposed in-line and/or at selective angularity, and intermediate free-standing pylon peripheral units and bridging canopy peripheral units.

Computer implemented method for making a die includes: selecting coating uniformity required to produce a particular coated product with the die and a value for one or more dimensions of the die; determining (using a mathematical model determined by regression analysis) total indicated run-out (TIR) of a die surface and dimensions of the die not having a user specified value; and machining die part or parts to the determined TIR and dimensions. A thermal treatment process for reducing the number of finishing (e.g., grinding) cycles needed to produce a desired die flatness is provided. A coating fluid rheological characteristic can be an input to the method.

Methods and apparatus (40) to neutralize the charge on a moving web (42) by splitting the field present on the web (42). One portion of the field is removed by a grounded element (55a, 55) proximate to, and optionally contacting, one side of the web (42). Proximate the opposite side of the web, the apparatus includes an ion source (57a, 57b, 57c), which provides ions to the web (42) to neutralize the charge remaining on the web (42), and a second grounded element (50a, 50b, 50c) positioned between the ion source (57a, 57b,57c) and the web (42). The methods provide a web (42) that is net neutralized and is also dual-side or bipolar neutralized.

Optically clear adhesive or coating layers can be prepared by preparing a curable mixture, coating the curable mixture to form a layer, partially curing the curable mixture, drying the coated layer, and fully curing the curable mixture. The curable mixture may also be partially cured and then coated, dried and fully cured. The curable mixture includes two free radically polymerizable monomer compositions that are relatively incompatible and a transient compatibilizer, such as a solvent. Polymers of the two monomer compositions, if polymerized separately and blended, form phase separated domains. The curable mixture provides for adhesive or coating layers that are optically clear.
