摘要： 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.

摘要： Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a frame including a plurality of vertical members and a plurality of horizontal members, each vertical member and horizontal member having an inner side and an outer side; a sterilization wrap, a first portion of the sterilization wrap positioned adjacent the inner side of each vertical member and each horizontal member to define a volume and an opening to access the volume; and a lid for sealing the volume against an ingress of contaminants. Additionally, a sterility gauge for signaling whether the volume is sealed against contaminants also may be provided. Exemplary sterilization packaging systems may include other features as well.

摘要： 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.

摘要： 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.

摘要： A method and associated system are provided for cutting and placing individual nose wires in a facemask production line. A continuous wire is supplied from a supply source to a cutting station in the facemask production line where the continuous wire is cut into individual nose wires having a defined length. A first web is conveyed to a vacuum conveyor, and the individual nose wires are deposited from the cutting station onto the vacuum conveyor such that the nose wires are drawn by vacuum against the first web at a defined spacing and orientation. With the vacuum conveyor, the first web and attached nose wires are conveyed to a folding station wherein the first web and nose wires are combined with a second web such that the nose wires are encapsulated between the first and second webs.

摘要： A method and system are provided for placing nose wires in a facemask production line. A supply of individual pre-cut nose wires are supplied to a dispenser in the production line. With the dispenser, the nose wires are metered at a defined spacing and orientation onto a running carrier web that is conveyed past the dispenser. The carrier web and nose wires deposited thereon are conveyed to a folding station wherein a binder web is folded over an edge of the carrier web such that the nose wires are encapsulated between the binder web and the carrier web.

摘要： 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.

摘要： Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a sealing assembly, where the sealing assembly includes a sheet of sterilization material and a clamp for sealing the sheet of sterilization material against a container to seal the volume of the container from contaminants. Also provided is a sealing assembly including a sheet of sterilization material and a clamp having open position and clamped positions. The clamp is configured to extend about a perimeter of a container, the sheet of sterilization material is disposed between the container and the clamp when the clamp is in the clamped position to seal a volume of the container, and the clamp is held in the clamped position by a latch. Exemplary sterilization packaging systems may include other features as well.

摘要： 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.
