Abstract: Apparatus for electronically controlling the application of dyestuffs and other liquids to moving textile materials to provide a printed pattern thereon. The system includes electronic circuitry for periodically receiving bits of pattern data and processing the information to operate a plurality of valves which control the flow of liquid into the materials. Means are provided for dispensing equal amounts of liquid across a line of textile material to those areas of the material which are to receive the liquid. These equal amounts also may be uniformly varied to change the amount of liquid applied to those areas. Furthermore, means are provided for applying additional amounts of liquid to only certain of those areas which are to receive liquid, thereby dispensing unequal amounts of liquid to such areas.

Also, apparatus for forming a unitary strip including interdigitating gripper means arranged in an oval path, means for advancing the gripper means around the oval path, and means for increasing the degree of interdigitation of the gripper means during a portion of their advancement around the oval path.

Abstract: Method and apparatus to produce a bonded loop pile carpet. The carpet machine is of the rotary type which uses cooperating notched blade members to form the yarn loops for bonding to a backing sheet. One set of the blade members is reciprocably mounted in the rotor of the machine.

Abstract: An improved circular knitting machine which provides for semiautomatic doffing of large diameter rolls of knit fabric. The doffing of the fabric can be accomplished by a woman operator without strain. The improved circular knitting machine provides a quick diconnect from the drive to take the tension of the machine to allow machine repair without extensive dismounting of the machine.

Abstract: The present invention concerns a method for the manufacture of laminated packing material containing at least one layer of a metal foil, e.g., aluminum foil, and a layer of plastic material applied to the said metal foil. The invention also concerns an apparatus for the realization of the method for the manufacture of laminated packing material.

Abstract: An improved circular knitting machine which provides for semi-automatic doffing of large diameter rolls of knit fabric. The doffing of the fabric can be accomplished by a woman operator without strain. Further, the improved circular knitting machine provides an oxbow rod to prevent pattern skewing and a control means to coordinate the fabric take-down speed with the fabric take-up speed. The semi-automatic doffing apparatus includes a doffing handle, the inside of which is grooved to accommodate the take-up roll shaft, so that the full roll of fabric can be easily removed from the knitting machine.

Abstract: Apparatus to apply dyestuff to a moving sheet of fabric which employs a unique construction of dye applicator or gun constructed basically in two clam shell sections with the clam shell sections being made in sets for ease of adjustment and installation. The dye applicator or gun includes a multiplicity of dye jets made by grooving each of the clam shell sections, mating the sections and then drilling the grooves to the proper size.

Abstract: An improved circular knitting machine which provides for semiautomatic doffing of large diameter rolls of knit fabric. The doffing of the fabric can be accomplished by a woman operator without strain. The knitting machine has a unique spreader bar to allow slitting of the fabric for inspection purposes while the fabric is being knit. The unique spreader bar includes a support member having a wheel member and a convex portion adjacent the wheel member to guide a fabric around the wheel.

Abstract: A dust control mat having a pile fabric upper surface and a bottom calendered rubber stock sheet which employs an anti-tear strip located perpendicular to the grain or calendered direction of the rubber stock sheet between the rubber sheet and a latex backing on the pile fabric. A novel method is employed to produce the mat in which the reinforcing tear strip is located in position prior to vulcanizing the rubber stock sheet in an autoclave.

Abstract: Method to cut or shear loop pile fabric by moving the loop pile fabric to be cut or sheared over a rotating cutting member which cuts the loops in the fabric but prevents the fabric backing material from being cut by the use of guard members for the cutting blades.

Abstract: A wet mop head construction comprising a pile fabric having a central headband for attachment to the gripping elements of a wet mop tool and a flared main body portion extending freely therefrom for contact with a surface, such as a floor, to be cleaned.

Abstract: Apparatus to cut or shear loop pile fabric by moving the loop pile fabric to be cut or sheared over a rotating cutting member which cuts the loops in the fabric but prevents the fabric backing material from being cut by the use of guard members for the cutting blades.

Abstract: Method to cut or shear loop pile fabric by moving the loop pile fabric to be cut or sheared over a rotating cutting member which cuts the loops in the fabric but prevents the fabric backing material from being cut by the use of guard members for the cutting blades. The cutting member is comprised of a plurality of modules which contain blanks at each end of the cutting member to prevent cutting of the selvedge of the fabric.

Abstract: A circuit for use with a control system in which interleaved pairs of records and parity characters following each interleaved pair of records are recorded on magnetic tape, with each of the interleaved pairs of records having at its ends a stop-command-forward character and a stop-command-reverse character, the circuit comprising gate means for passing read data from a magnetic tape reader to a utilization device, means for identifying the stop-command-reverse character and the stop-command-forward character, and a flip-flop for disabling the gate means in response to identification of one of the stop-command-characters at the end of a record and for enabling the gate means in response to identification of a different stop-command character at the beginning of a next record.

Abstract: Method and apparatus to pre-sterilize the filling. tube of a packaging machine which produces filled flexible packages. The pre-sterilization is carried out by generating ozone within the confines of a tubular web of packaging material and recirculating the ozone through the filling tube while generating more ozone for sufficient time to pre-sterilize the machine.

Abstract: Process and apparatus for the pattern dyeing of moving pile fabrics such as carpets, by the application of plural, continuously flowing dye streams, wherein the dyes are applied in multiple discrete small increments from the streams and control means are provided for accurately positioning the points of application of the dye increments in the pile fabrics to obtain sharp, detailed intricate patterns.

Abstract: Method and apparatus to score cut the hardbacking of carpet tiles to relieve the inherent stresses therein to alleviate the tendency of the carpet tiles to pucker when laid in operative position on the floor. The back of the carpet tiles are cut by a serrated die cutter to produce an undulating configuration in the backing of the carpet tile.

Abstract: Method and apparatus to measure an amount of yarn delivered from a warp beam for a knitting machine to periodically trigger a comparison device to compare the theoretical number of courses to the actual number of courses knit from the measured length of yarn to develop an electronic signal which is used to adjust the let-off control of the knitting machine.
