  • Patent number: 11059690
    Abstract: An automated method and system for stacking and loading wrapped or unwrapped facemasks into a carton in a facemask production line includes conveying individual wrapped facemasks in a continuous stream to a stacking location. At the stacking location, the facemasks are deposited into a vertical accumulator such that the facemasks are stacked in the accumulator. Upon reaching a predetermined fill level of facemasks in the accumulator, a bottom retainer in the accumulator is opened such that the stacked facemasks drop into a carton placed below the accumulator. Upon opening the bottom retainer, a mid-level retainer is actuated in the accumulator that captures facemasks that continue to be deposited into the accumulator at an intermediate height above the bottom retainer. The bottom retainer is closed after the stacked facemasks drop into the carton, and the mid-level retainer is then opened such that the facemasks captured by the mid-level retainer drop onto the bottom retainer.

  • Patent number: 10913559
    Abstract: An automated method and system for stacking and loading wrapped facemasks into a carton in a facemask production line include conveying individual wrapped facemasks to a delivery location adjacent to a rotary wheel, the rotary wheel conveyor having individual pick-up devices spaced around a circumference thereof. Each wrapped facemask is picked-up with a respective pick-up device on the rotary wheel conveyor and transported to a first carton staging area at a first location on the circumference of the rotary wheel. At the first staging area, the facemasks are released from the rotary wheel conveyor and deposited into a carton.

  • Patent number: 10882715
    Abstract: A method and system are provided for splicing a reserve nose wire to a running nose wire in a facemask production line. Prior to depletion of the running nose wire, a reserve nose wire is brought up to a transport speed in a conveying direction of the running nose wire. At or near a zero relative speed between the running nose wire and the reserve nose wire, a leading end of the reserve nose wire is introduced onto the running nose wire, and the two wires are spliced together. The running nose wire is then cut upstream of the splice location such that the reserve nose wire becomes a new running nose wire in the production line.

  • Patent number: 10828842
    Abstract: A method and associated system for cutting and placing individual nose wires in a facemask production line include supplying a continuous wire from a supply source to a cutting station where the continuous wire is cut into individual nose wires having a defined length. The nose wires are then conveyed to a treatment station prior to being deposited onto a carrier web. At the treatment station, a surface treatment is performed on a side of the nose wires that results in an increased surface attachment of the nose wires to the carrier web.

  • Patent number: 10492547
    Abstract: A method and associated method are provided or introducing a supply of reserve nose wires in a facemask production line prior to depletion of running nose wires in the production line. A first nose wire source and first cutter system are provided for supplying the running nose wires to the production line. A reserve nose wire source and second cutter system are staged in a stand-by state proximate to the first nose wire source. Prior to depletion of the first nose wire source, the reserve nose wire source and second cutter system are brought up to an operational speed while diverting nose wires from the second cutter system away from the production line. At operational speed of the reserve nose wire source and second cutter system, nose wires from the second cutter system are diverted to the production line while diverting nose wires from the first cutter system away from the production line.

  • Patent number: 10494221
    Abstract: A method and associated system are provided for splicing a reserve nose wire to a running nose wire in a facemask production line, wherein the running nose wire is supplied continuously from a supply roll. Prior to depletion of the running nose wire, the supply roll is moved from an operating location to an intermediate location that is further from the production line while continuing to supply the running nose wire from the supply roll. The supply roll is then moved from the intermediate location back towards the production line while decelerating the supply roll to a stop, thereby creating an accumulation of the running wire functionally between the supply roll and the production line. With the supply roll at a stop, the running nose wire is continuously supplied from the accumulation and a leading end of a reserve roll of nose wire is spliced to the running nose wire at a location upstream of the accumulation where the running nose wire is at a standstill.

  • Publication number: 20190321120
    Abstract: A probe cover is provided. The probe cover is formed from a film that defines a tubular sheath having a distal end and a proximal end defining a channel therebetween, where the distal end is closed and the proximal end defines an opening having a periphery; and a flange that extends from the periphery of the opening at the proximal end of the tubular sheath. The flange facilitates the secure attachment of the probe cover to a surgical drape, such as a surgical drape used in the operating room as an anesthesia screen or as a screen to separate the surgical sterile field from the non-sterile field. A method of using the probe cover in conjunction with a probe during a surgical procedure is also provided, where the method includes attaching the probe cover to a surgical drape. A surgical drape that includes the probe cover is further provided.

  • Patent number: 10314346
    Abstract: A multi-layered face mask coated with discontinuous patterns of phase change material are incorporated into the face mask construction to provide for cooling of the microclimate in the dead space of the face mask. Optimized cooling is achieved by strategic placement of layers coated with a phase change material within the mask construction and the amount and density of the phase change material in contact with the temperature sensitive areas of the face, as well as areas experiencing the maximum amount of flux from exhaled breath. The shape of the mask can also be adjusted to increase skin contact with the phase change material and decrease dead space volume, which reduces the volume of warm exhaled air and can provide sufficient cooling with less phase change material. The discontinuous patterns of phase change material also provide inter-layer spacing between the layers of the mask, which can improve splash resistance.
