Benefits of technology
[0006]Therefore, it is an object of the invention to provide a simple, effective and inexpensive way of accurately filling pillows, cushions and other filled containers with a fill material entrained in a moving air stream.
Problems solved by technology
These devices may be quite accurate, but require an amount of time to dispense and weigh the fill material, during which the filling process cannot occur.
These systems are relatively slow, complex and expensive.
However, such operators are in short supply, and a change in pillow or cushion size, shape or fill density can result in a large amount of wasted time and material before the operator is sufficiently trained to a proper level of consistency.

Embodiment Construction
[0034]Referring now specifically to the drawings, an apparatus according to a preferred embodiment of the invention is shown at broad reference numeral 10, and includes a fiber opener 12, for example, a Fiber Controls staple fiber opener. One typical staple fiber suitable for use is a 1.5 inch staple, 7 denier polyester fiber. As noted above, many other fibers, synthetic and natural, as well as other materials such as feathers, down and foam are also suitable for use with this method, although the manner of processing the materials for being entrained in the air stream may differ.
[0035]The opener 12 separates the fibers, which are typically in large clumps, and prepares them for being introduced into a moving air stream. After opening, the fibers are conveyed into a manifold 14 that is connected to a pair of blowers 16, 18. Flow of fibers from the opener 12 and manifold 14 to the blowers 16, 18 is controlled by a pair of shut-off, or “blast” gate assemblies 20, 22 positioned between...

Abstract
An apparatus for filling containers with loose fill material, comprising an opener for opening the fill material into a separated condition suitable to be injected into the container. A blower communicates with the opener for entraining the opened fill material in a pressurized air stream, and a nozzle communicates with the blower for directing the pressurized air stream and entrained fill material into the container. An air pressure gauge operatively communicates with the pressurized air stream for determining the pressure in the air stream and an increase in air pressure indicative of a predetermined amount of fill material in the container. A flow controller communicates with the pressurized air stream for starting and stopping the injection of fill material into the container.
Description
TECHNICAL FIELD AND BACKGROUND OF INVENTION[0001]This invention relates generally to filling containers with staple fiber entrained in a moving air stream. More particularly, the invention relates to filling items such as pillows and cushions with staple fiber entrained in a moving air stream, such as in a manufacturing process wherein bedding, furniture and similar products are made. For the purpose of illustration and explanation, the invention of this application is described with relation to the filling of a pillow with a predetermined quantity of fill material. It will be understood that when the term “container” is used, it is used in the sense of a flexible case, envelope, bag or the like, usually formed of fabric, in which the fill material is contained, and which increases in volume as the fill material enters the container. A pillow is one such “container.” The term “tick” is a term of art that refers to a fabric envelope, such as a pillow, that is left with an opening of ...
