Abstract:
A process for applying glue and brazing material to a honey-comb body includes coating structured metal sheets with adhesive or binder at given positions of zones of the metal sheets to be subsequently coated with brazing material and brazed. Subsequently, the metal sheets are layered or wound into a honeycomb body having a multiplicity of channels for the passage of a fluid. A continuously adhering brazing powder is applied to all of the given positions of the layered or wound body. Excess brazing powder is shaken or blown out of the body. A corresponding device includes a transport path for structured sheets and rotatable sponge-like rollers to be saturated with adhesive or binder. The rollers are disposed laterally alongside and/or above and/or below the transport path. The rollers are rotatable by a transport motion of the sheets or drive mechanisms are provided for rotating the rollers.
Abstract:
An apparatus and method for fabricating corrugated composite stiffeners provides a base tool having grooves formed in an outer surface and a roller having a rotating shaft and a removable, lobed, elastomeric member surrounding the shaft. The lobes of the elastomeric member form a radial array around the shaft and match the contours of the grooves in the base tool. A section of prepreg fabric is placed between the roller and the base tool, and the roller is rotated to sequentially engage the lobes with the grooves, the lobes pressing the fabric into the grooves, the fabric conforming to the contours of the grooves. Several layers of fabric are applied, then the elastomeric member is released from the shaft, laid out flat, and placed on the fabric on the base tool, the lobes locating in the grooves. The base tool, fabric, and elastomeric member are enclosed in a vacuum bag and heated to cure the fabric.
Abstract:
A method of making a sensible and latent heat exchange media having a multiplicity of passages therethrough through which an air stream can flow, the method comprising impregnating a solution containing at least one of the group consisting of sodium silicate and potassium silicate into corrugated cellulosic paper to provide silicate impregnated paper and reacting the silicate in the impregnated paper using a gas such as CO2 or an acid such as boric acid to form a silica gel desiccant, thereby forming a sensible and latent exchange media.
Abstract:
The present invention is a machine to perform two or more processes to an bottle wherein registration of the first process to the second process is required. The products produced with such registration have distinct advantages over prior art. These include labeling systems comprising multiple labels that can be incorporated into many useful variants for promotional items. Additionally, novel packaging systems can utilize this technology.
Abstract:
This composite uses the bonding of PVC to a variety of materials, from cloth to concrete, by the simple laying of the PVC surface to the other surface without the use of conventional wet, tacky, intermediate layer or layers of conventional adhesives. A simple preapplication of a chemical intermediate to the second surface in latex form and dried to a nontacky state is done. This is followed in any length of time thereafter with the simple contact of both surfaces, one to the other. A mild to aggressive tack bond, or a hard permanent joining of both surfaces is achieved. This bond is formed by the polar attraction of certain acrylics to the plasticizers in the PVC.
Abstract:
A corrugator single facer of the type utilizing a large diameter bonding and corrugating roll and a small diameter corrugating roll is driven without direct drive applied to either corrugating roll. Instead, the pressure belt arrangement which supports the lower corrugating roll to provide the nipping force includes a series of driven supporting pressure belts that are loaded against the lower corrugating roll and which transmit rotational movement thereto and through the nip to the large diameter bonding roll.
Abstract:
A method and an apparatus for manufacturing corrugated boards are disclosed. The method may include the steps of supplying a first web of medium having a first and second sides, wherein each side of the first web having a plurality of flutes, and wherein each flute having a crest, applying a wetting agent and an adhesive composition in a sequential fashion to the plurality of flutes on the first side of the first web, and securing a second web of medium is to the plurality of crests on the first side of the first web to form a single-faced corrugated board.
Abstract:
An guide arm apparatus to guide endless ribbon into the web of a corrugating machine, said apparatus having automatic control for placing and positioning the endless ribbon
Abstract:
The present invention relates to a method of forming a laminated material comprising the steps of corrugating a paper sheet and applying a liner to one or both sides of the corrugated sheet, wherein the liner is a pre-made laminate of a paper backing and plastic film which is metalized on one side and corona or chemically treated on the other side. A laminating apparatus for use in the above method is also described herein, which includes a means for feeding out a paper sheet and a liner to a set of corrugating rollers, the liner being a pre-formed laminate of paper and plastics film, and means for uniting the paper sheet and liner immediately subsequently to the corrugation of the paper sheet.
Abstract:
A filter element formed of a pleated filter medium (11) and having a seal or gasket element (15) on its periphery or end faces. On one side of the filter element, which may represent either the inlet or the outlet side of the filter element, at least one adhesive track or reinforcing member (12, 13, 14), and preferably at least two adhesive tracks or reinforcing members (12, 13, 14), is/are arranged in such a way that the filter element can be bent to a curved configuration in one direction.
