A fabric power door with a vertical or side-winding curtain includes window comprised of a transparent sheet that is attached to the curtain by way of a flexible frame. The transparent sheet is appreciably smaller than the window opening in the curtain to create a strain-relieving gap between the sheet and the curtain. The flexible frame extends across the gap and overlaps both the curtain and the transparent sheet. As the door opens and closes, the flexible frame protects the transparent sheet from stresses from the flexing movement of the curtain.

An example of a door curtain having pieces comprised of different thermoplastic materials includes a weld medium that facilitates the welding of two thermoplastics that are otherwise not readily welded together. In some examples, the weld medium comprises two outer layers that are joined to each other, wherein one layer is of the same polymer as one of the curtain pieces, and the other opposite layer is made of the same polymeric material as that of the other curtain piece. The weld medium is sandwiched between the two curtain pieces such that matching materials of the curtain and weld medium face each other. The two curtain pieces, with the weld medium between the two, are then thermally or ultrasonically welded together. The weld medium can be made by coating a fabric sheet with the two different plastic layers bonded to opposite sides of the fabric sheet.

An example of a door with a pliable curtain includes various washdown features that make the door particularly suitable for use in food and drug related environments that demand cleanliness. To prevent product contamination, such as bacteria and other microorganisms, some examples of the door include a curtain storage track with a spiral groove machined in a unitary block of plastic, a ventilated side frame with a removable curtain guide track and a removable seal, and various curtain seams that not only join multiple sheets of the curtain together but also promote and strategically direct liquid runoff to avoid creating water-holding surfaces and to prevent liquid from dripping on products passing through the doorway.

A method in which user generated video content is distributed over a peer to peer network as live broadcast but may be viewed at any point using 2 overlayed peer networks. Video is rendered during download and a user may request a specific point in the video content and that point and all subsequent video content will be downloaded and rendered first via a peer to peer network.

Defect localization can be performed in integration tests to more efficiently determine if recent source code changes caused a defect. Change locations are identified that represent code changes (e.g., source code changes) that occurred since a last integration test run. Code coverage information can be obtained indicating lines of code actually tested during the integration test. A search can be performed to find an intersection between the code changes and the code actually tested to determine one or more candidate code changes that may have caused a defect in the integration test. The candidate code changes can be ranked based on one or more different ranking algorithms.

A folder and method for folding plastic bags includes at least one folding station. The folding station has a folding point where an input, an output and a storage portion meet. The bag travels in the input portion in a different direction than in the storage portion. The output direction is substantially the same as the input direction. A turning air source is disposed to direct the bag into the storage portion and an air source is disposed to direct the bag into the output section. A fin helps guide the bag into the output portion. A turning roll disposed above the turning point, and imparts motion to the bag, generally in the storage direction. A second folding station, similar to the first, is downstream the first folding station. The output direction for the first station is the same as the input direction for the second station, and the bag path between the first and second folding stations is substantially linear. A separator located upstream of the folder includes a separator nip formed by separator rolls that are in, and remain in, the film path in one embodiment. A slow-down section includes servo-driven slow down rolls with projections there on.

Example systems and methods for aligning roll-up door curtains are disclosed. An example door includes a roller that is rotatable about an axis. The door further includes a curtain having a wrapped section wrapped around the roller and an unwrapped section extending tangentially away from the wrapped section. The unwrapped section adjoins the wrapped section at a first point proximate a first end of the roller and at a second point proximate a second end of the roller. The axis is closer to the second point than to the first point when the curtain is at the intermediate position. In some examples, the door includes a guide member to guide the curtain on to the roller.

摘要:
A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have, connected thereto, a source of power that is at an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire may be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones may include temperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic, microwave or radiative energy.
