Embodiment 1

[0054] In this embodiment, the panels are formed by a roll forming process. The material may be in the form of long strips coiled onto spools. In one embodiment, the material may be preheated to a temperature of less than about 140° C. to provide sufficient strength to the material to be handled during the panel manufacturing process and to prevent the material from being heated to temperatures during the panel manufacturing process. Undue shrinkage at higher temperatures. Ideally, shrinkage of the material during manufacture of the panels is minimized since the dimensions of the finished panels should permit the panels to be successfully mounted to the brackets. Where the bracket has a groove configured to receive and retain the flange of the panel, it will be appreciated that the size of the finished panel is of particular importance and including low temperature preheating of the material prior to fabrication of the panel can advantageously prevent or limit Excessive shri...

Embodiment 2

[0084] Figure 10 A schematic diagram showing an example of a continuous process and apparatus for forming panels using a heated mold. In this embodiment, the material 103 is in the form of an elongated strip 105 wound onto a reel 101 . In one embodiment, a coil coupling device 159 is provided for coupling material at the end of one coil to material at the beginning of another coil, thereby enabling the material to be continuously conveyed through the heated mould. The loop coupling device 159 may staple the loops together, glue them together, tape them together, or sew them together, or may couple the loops together in any other known manner. For example, in certain embodiments, the coil joining device may include an ultrasonic welding device, such as an ultrasonic knife, for simultaneously splicing and cutting material.

[0085] In the illustrated embodiment, the material is pulled from the spool toward and through the heated die by a pulling device 189, which may include ...

Embodiment 3

[0107] Figure 13 Another example of a process and apparatus for producing linear panels according to aspects of the present disclosure is shown. For example, a panel can look like Figure 11 and Figure 12 panel shown. This embodiment is similar to Embodiment 2 described above, and only the differences between the two embodiments will be described in detail.

[0108] In this embodiment, like the previous embodiments, the material 103 is in the form of an elongated strip 105 wound onto a reel 101 . In one embodiment, a coil coupling device 159 is provided for coupling material at the end of one coil to material at the beginning of another coil, thereby enabling the material to be continuously conveyed through the heated mould. In this embodiment, the coil coupling device comprises an ultrasonic welding device comprising an ultrasonic knife for simultaneously heating and cutting material.

[0109]The material is drawn from the spool toward and through the heated die by pul...

Abstract

A method of forming a linear panel from a thermoformable fibrous material by a continuous process comprises: continuously drawing an elongate strip of thermoformable fibrous material through a heatingstation to heat the material; forming the heated material into a desired panel shape; and continuously drawing the material through a cooling unit in order to cool the material after the material hasbeen formed into the desired panel shape.

Description

technical field [0001] The present subject matter relates to the manufacture of linear panels, and in particular to linear panels formed from thermoformable fiber material and suitable for ceiling or wall installation. Background technique [0002] Linear panels formed from metals such as aluminum are known in the art. The length of the linear panels is significantly greater than their width, which length is usually at least twice the panel width, and usually at least five times the panel width. [0003] Linear panels formed from metals such as aluminum have the advantage of being relatively light and flame resistant, but generally do not exhibit favorable acoustic properties. It will be appreciated that in many cases it may be desirable to provide ceilings or walls with good sound absorbing properties. This need can be addressed by providing panels that are non-metallic or only partially metallic. Accordingly, methods for making improved non-metallic or only partially me...
