Abstract:
Systems and methods for producing consistent spray patterns and for diminishing clogging experienced when applying spray adhesive from a spray gun are provided. One system includes an automatic non-atomizing spray valve operably coupled to a first and second flow valve. The spray and flow valves are electronically controlled using logic running on a processing unit. The logic is programmed to carry out a spray cycle that involves dispensing a first liquid from the spray valve (first phase) and then dispensing a second liquid through the same spray valve (second phase). Because the first liquid (e.g., water-based adhesive) has the potential to clog a nozzle of the spray valve, a short burst of the second liquid (e.g., cleaning fluid) is introduced to prevent the nozzle from clogging. The spray valve is configured as a pulse width modulated spray gun to further reduce clogging and to generate an evenly distributed spray pattern.
Abstract:
A multi-needle quilting machine is provided with a tape or ribbon guide that is operated by a method by which a narrow strip is fed against a facing layer of a wide multi-layered material as it is fed into the quilting machine. In the quilting machine, series of chain stitches are sewn, at least one of which joins the tape and layers of the multi-layered material together with the same thread in a quilting process, thereby applying the tape to the quilted product in a single quilting operation without the need for a post-quilting tape application step. The tape may form a decorative strip or have unsewn sections that serve as handles for a mattress when the quilted product is formed into a mattress cover.
Abstract:
A mattress age indicating device includes an enclosure and an indicating assembly contained within the enclosure. The age indicating device may be configured to present an indication related to the mattress's age and may be coupled to the mattress or other bedding or seating product.

Abstract:
A method of making a multi-layer border for use in a bedding product, such as a mattress, is disclosed. The layers are secured together without the use of heat, thereby enabling the process to be stopped and started as desired without the worry of burning the materials. Pressure is applied to the multi-layered material in the form of pinch rollers to secure the layers together. One of the layers comprises an outer ticking material. As many layers of foam and/or fiber as desired may be included, provided a layer of doubled-sided adhesive is sandwiched between adjacent layers. A backing may comprise the innermost layer.
Abstract:
Apparatuses, methods, and computer program products for quilting webs without compressing the webs. A quilting machine includes a needle bar to which needles are attached, needle thread passing through each needle, a looper shaft to which loopers are attached, a looper corresponding to each needle and from which looper thread is provided to form stitches, and a retainer bar to which spreaders are attached to facilitate stitching. A drive pulley powered by a first servo motor rotates cranks to move the needles through a cycle and rotates a belt which rotates an indexer pulley. Rotation of the indexer pulley oscillates the looper shaft and reciprocates the retainer bar. Another drive pulley powered by a second servo motor operates to move an input web through the machine between chain stiches.
