Provided is a tube joining apparatus that allows a user to easily and properly set tubes to be joined, and can prevent occurrence of joining failures due to tube setting errors. A tube joining apparatus 1 includes a housing 10, a lid 22 relatively movable toward and away from the housing, a tube holding part 23 that holds a first tube T1 and a second tube T2 individually in a state of being placed side by side in an oblique direction D1 with respect to a height direction Z of the housing, and a tube pressing part 25 that presses the first tube and the second tube against each other as the lid relatively moves toward the housing.

A fusion machine which can be top-loaded on very large polyolefin pipes and pipelines has jaws which consist of an upper half jaw and lower left and right complemental jaws which pivot on the half jaw. Left and right actuators connected between the complemental jaws and the half jaw operate in one direction to cause the complemental jaws to rotate to an opened condition in which the upper half jaw can be lowered onto and lifted from the pipes to be fused and in the other direction to cause the complemental jaws to rotate to a closed condition in which the pipes to be fused are gripped so substantially around their circumferences as to resist their deformation from round during manipulation by the machine. The top-loading machine minimizes the need for heavy equipment to load and unload pipe to and from the fusion machine.

A device for welding thermoplastic tubes to a welding method, and to a welding knife. The device is provided for welding thermoplastic tubes, wherein the tubes are placed into tube holders and squeezed with the aid of tube clamps. A welding knife is moved between the first and the second tube holder and severs the tubes in the process. Cut ends and residual ends are thereby produced. The cut ends are aligned with one another by a relative movement of one tube holder with respect to the other tube holder and, by a horizontal movement of the two tube holders, are welded simultaneously to form continuous tubes.

Systems and methods are disclosed that include an operation chamber, a plasma generator having at least one plasma head disposed within the operation chamber and in proximity to a profile formed by cutting a piece of tubing, and a mechanical motion module. The plasma generator generates a plasma treatment and applies the plasma treatment via the at least one plasma head to the profile to activate material on an end surface of the profile, within a lumen of the profile, or a combination thereof. Once the material of the profile is activated by the plasma treatment, the mechanical motion module manipulates the profile to close the lumen of the profile to aseptically seal the profile.

A window frame assembly for installation within a garage door having front and rear exposed surfaces and one or more window openings. The assembly includes front and rear window frame members which are installed within the door openings in the garage door. The front and rear members are brought toward each other to sandwich the borders of each of the window openings while also capturing an associated transparent pane. A series of fastening members are used to hold the front and rear frame members securely against each other. The front and rear window frame members are made of synthetic polymeric starting stock starting materials which, together with the transparent panes, are able to withstand hurricane force winds and associated blowing debris.

A welder for constructing and welding plastic fenestration structures, including parts storage bins structured to store and support parts to be assembled to create the plastic fenestration structures; wheels that receive the parts from the parts storage bins; aligners that position the parts relative to one another; heating plates that apply heat to ends of the parts thereby rendering at least a portion of the ends of the parts molten; parts shifters operably shiftable between a first position adjacent the wheels and a second position remotely located from the wheels that shift the parts to a fusing position in which adjacent parts are abutted together at a fusing station to produce the plastic fenestration structure; and at least one cooling station at which the plastic fenestration structure is held.

A portable assembly for securing a plastic fitting to a plastic pipe by employing fusion or thermal sealing is disclosed. The assembly is secured to the outer circumference of a plastic pipe at a desired location. The assembly can be secured at any longitudinal and lateral position along a plastic pipe. A heater heats both the pipe and the fitting to the point where they begin to melt. The heater is then removed and the fitting is pressed onto the surface of the pipe, thus fusing the fitting to the pipe. After cooling, the assembly is removed and the surface of the pipe within the interior of the fitting is drilled or removed. This now enables fluid within the pipe to be sent to the fitting and onto distribution lines which are connected to the fitting.

An apparatus for manufacturing a bagged electrode includes a conveying unit, a first bonding unit, a second bonding unit, and a separating unit. The conveying unit conveys an electrode in a manner interposed between a pair of long separator materials unwound from a pair of rolls. The first bonding unit bonds the pair of long separator materials outside the electrode along a conveyance direction without stopping conveyance of the electrode and the pair of long separator materials. The second bonding unit bonds the pair of long separator materials outside the electrode along a direction intersecting the conveyance direction without stopping conveyance of the electrode and the pair of long separator materials. The separating unit cuts the pair of long separator materials along the direction intersecting the conveyance direction to cut off the bagged electrode without stopping conveyance of the electrode and the pair of long separator materials.

A tube joining device which is capable of preventing occurrence of a joining failure. The tube joining device includes: a first tube holding portion for holding a first tube; a second tube holding portion for holding a second tube; a tube superimposing portion that aligns the first tube and the second tube; and a switching mechanism switching from a state of holding the second tube to a state of releasing the second tube.

Provided is a tube joining device that allows a user to easily and appropriately perform setting of tubes which become a joining target, and is capable of preventing occurrence of a joining failure caused by a setting error of the tubes in advance. A tube joining device 1 includes: a first tube holding portion 41 that is capable of holding a first tube T1; a second tube holding portion 42 that is disposed in adjacent to the first tube holding portion, and is capable of holding a second tube T2 at a position that is parallel to the first tube; and a housing 2 that is provided with a cover member 20 that is closed to cover fusion-joining sites C of the first tube and the second tube. The cover member is slidable along a direction in which the first tube and the second tube are disposed in parallel.
