Abstract:
A method and apparatus for forming glass fibers is disclosed. The method of the present invention involves passing a narrow, high velocity air stream horizontally below the bushing to thereby induce and entrain additional air flow from the environment surrounding the bushing into this air stream to flow generally horizontally below the bushing. Suitable apparatus, such as an air amplifier, is employed to produce this desired result.
Abstract:
A strand deflector used in the manufacture of continuous strands is shown and described. The deflector comprises a rigid surface which stretches across the width of the mat making machine and which is interposed between the strand feeders located above it and the mat making surface so that the strands fed toward the surface must deflect from the deflector surface before they are collected on the mat making surface. The deflector surface is adjustable in the vertical direction and the angle of deflection with respect to the flow of strand from the feeder may also be changed to any desired value.
Abstract:
An apparatus for producing glass fibers is disclosed. The apparatus includes means associated with an applicator for moving the glass filaments from the surface of the applicator when waste filaments are being produced such that the glass filaments are brought into contact with the application surface for coating the filaments with a binder and/or size only when production quality strand is being produced. This substantially reduces binder and/or size consumption and prevents the operator of the forming position from coming into physical contact with the binder and/or size coated strand.
Abstract:
An improved method and apparatus for forming chopped glass fiber strands is disclosed. The improvement comprises a vibratory conveyor under a drying apparatus for said glass fiber strands which is insulated such that cold spots do not develop on the tray adjacent the glass fiber strands. Preferably, the tray is formed of two sections, one inside the other, having an airspace therebetween along their lengths and having a spacer between the lips of the sections.
Abstract:
Apparatus and systems for transporting a generally cylindrical package include: (a) a frame including a support device having at least one compressible support member and a pivot device for pivoting the support device about a generally vertical axis, the support device being movable along the generally vertical axis between (1) a first predetermined position spaced apart from and below an outer surface of a generally cylindrical package which is removably telescoped upon a generally horizontal member of a support at a first predetermined location and (2) a second predetermined position in which the compressible support member contacts and supports at least a portion of the outer surface of the generally cylindrical package; and (b) a carriage assembly connected to and supporting the frame, the carriage assembly including a carriage for moving the frame between (1) a first predetermined position proximate the support and (2) a second predetermined position horizontally spaced apart from the first predetermined position such that the generally cylindrical package is removed from the first predetermined location upon the generally horizontal member of the support and transported to a second predetermined location horizontally spaced apart from the first predetermined location.
Abstract:
A fiber glass bushing is described which produces hollow glass fibers from a multiplicity of tips having air tubes centered inside of them. Modules for providing a common header for rows of tubes centered in rows of tips on the bushing bottom are shown along with means to maintain the tubes centered during the running of the bushing.
Abstract:
A method and apparatus is disclosed for drying and conveying chopped glass strands. The system includes apparatus for controlling the temperature of the conveying means to thereby control the drying of the wet chopped glass strand and to avoid overheating of the glass strand.
