Abstract:
Ink jet printing is provided onto rigid panels such as foamboard and contoured material using ultraviolet (UV) light curable ink, which is first at least partially cured with UV light and then may be subjected to heating. Printhead-to-panel spacing is controllable to maintain a predetermined constant distance from the printing element to the surface of the panel where the ink is to be applied. Each of a plurality of printheads may be independently moveable to control the spacing of the printheads from the substrate surface. Sensors on the printhead carriage measure the shape, or vertical position of, the printhead's distance from the printhead carriage to the surface of the substrate being printed. The position or focal length of the UV light curing head may be varied to maintain focus of the UV light on the ink on a contoured surface of the substrate. UV curing heads may be located on the printhead carriage, one on each side of the printheads, and activated alternately as the carriage reciprocates, to spot cure and freeze the dots of ink immediately after being deposited on the substrate. Cold UV sources may be used to prevent heat deformation of flat or contoured substrates during printing, thereby making spot curing on heat-sensitive substrates such as foamboard possible.

Abstract:
Ink jet printing is provided using ultraviolet (UV) light or other curable composition or stable or other printable substance having a dye-component therein. The ink is jetted onto a substrate, the composition is cured, then heated to set the dye. Sublimation dye-based UV ink printing onto polyester is preferred.
Abstract:
Ticking for the production of mattress covers is preprinted with a plurality of different patterns by a computer controlled printer that prints in response to pattern data communicated from a control computer. The pattern data is organized and communicated by the computer so that a print head, for example, can scan the ticking material, such as in rows across the width of a web, and print different patterns. For example, different border panels can be oriented along a web and positioned side-by-side across a web and each printed with a different pattern. Top and bottom panels having corresponding patterns can be printed on the same or a different web. Identifying data for matching the panels of a mattress product can be provided in data files in the same or a different computer or can be printed on the fabric along with the patterns on the panels. The printed data can be manually or machine readable so that cutting and slitting of the panels from each other and the quilting and combining of the panels for assembly of a mattress product can be carried out manually or automatically.
Abstract:
An apparatus for stitching fabric to produce a quilted fabric having a needle plate for supporting the fabric, a presser plate located at a first position above the needle plate and a needle located above the presser plate. A needle rocker shaft is mechanically connected to the needle and imparts a reciprocating motion to the needle in response to the angular displacements of the needle rocker shaft. Further, a presser plate rocker shaft is mechanically connected to the needle rocker shaft and imparts a reciprocating motion to the presser plate in response to the angular displacements of the presser plate rocker shaft. The presser plate rocker has an output shaft movable to a different relative angular positions with respect to an input shaft in order to locate the presser plate at a second position with respect to the needle plate. The first and second positions of the presser plate provide respective first and second gaps with respect to the needle plate and permit fabrics of different thicknesses to be quilted.
Abstract:
A fluid sensing and distributing apparatus having a distribution plate and an indexing plate is provided. The distribution plate may include a first distribution face and a second distribution face and a plurality of ports extending between the first distribution face and the second distribution face. The first distribution face may further contain a plurality of arc grooves. The indexing plate may have a first indexing face, a first group of ports in fluid communication with the distribution plate arc grooves, a second group of ports in fluid communication with the distribution plate ports, and a first group of ports in fluid communication with a second group of ports. The apparatus has a means for driving rotational movement between the indexing and distribution plates. The apparatus may further contain a plurality of ports on the distribution plate in direct fluid contact with an external apparatus matching plurality of ports.
Abstract:
An apparatus (30, 40, 50) and a method of ink jet printing are disclosed that use a system for feeding a substrate longitudinally relative to a support area and a system for moving a printhead parallel to the direction of substrate feed. Indexing between transverse scan rows of a printhead (20) is carried out initially by the substrate feed system (16) and the actual feed distance is measured using an encoder or other substrate position measurement device (26). A controller (25) determines the amount of any error that occurs between the actual and the desired feed distances. The controller (25) then sends signals to move the printhead (20) to compensate for any error in the feed system feed. Compensating adjustments are then made to the next subsequent substrate indexing step so that the printhead tends to move back toward its home or zeroed position with its next correction and does not walk away from this home position as a result of cumulative movements. For printers that have bridges (17) moveable relative to the machine frame (11) on which the printhead (20) is carried, printhead motion is achieved by moving the bridge, for example, by actuating a linear servo bridge motion system (31). For fixed bridge roll-to-roll printers, the printhead (20) can be caused to shift longitudinally on the bridge (17) to make the correcting movements.

Abstract:
A quilting machine (10, 100, 200, 300, 400, 500, 600) is provided with a printing station (20, 125, 225, 325, 425, 525, 611, 626, 631) and a quilting station (44, 127, 227, 327, 427, 527, 627, 632), either on the same or a different production line. Ticking is preprinted with a plurality of different patterns, organized and coordinated by the computer so that a print head can scan the material and print different patterns of different panels (32). Identifying data (40) for matching the panels of a mattress product can be provided in data files and codes can be printed on the fabric. Panels can be matched and assembled into products based on the codes, and quilting, cutting, slitting and other operations can be controlled by printed codes and other data. The quilting and combining of the panels for assembly of a mattress product can be carried out manually or automatically using the data.
Abstract:
A quilting machine is provided having a first station and a second station, one being a printing station and one being a quilting station. The printing station is located either in line and preferably upstream of the quilting station, with a conveyor extending through each of the stations to convey a web of quilting material through the machine, or is off of the quilting line such that the material with a pre-applied pattern thereon is transferred, preferably in web form, to the line of the second station for the application of a pattern in registration with the first applied pattern. At the second station, for example, registration of a plurality of transversely spaced points is detected to determine longitudinal and transverse registration as well as skewing or rotation of the material, and the opposite transverse sides of the material are differently adjusted to orient and register the material. Where the second station is a multi-needle quilting station, different parts of the quilted pattern are applied in precise registration with the preprinted pattern. A master batch controller assures that the proper combinations of printed and quilted patterns are combined to allow small quantities of different quilted products to be produced automatically along a material web.
