    摘要： A die plate changing system holds first and second die plates and selectively transitions the first and second die plates into and out of communication with a material source. The die plate changing system has a frame having a body defining a first recess that receives the first die plate and a second recess that receives the second die plate, where the frame is heats the first and second die plates when the first and second die plates are disposed in the first and second recesses, respectively. The die plate changing system also includes a movement assembly operably coupled to the frame and that selectively moves the frame between a first position, where the first die plate receives material from the material source, and a second position, where the second die plate receives the material from the material source.

    摘要： Plant for producing non-woven fabric, which comprises a cooling chamber provided with a first and with a second cooling section traversed by filaments of non-woven fabric. In addition, the plant comprises a feed duct connected to the cooling chamber in order to convey, within the latter, a cooling gas by means of the action of a fan, and provided with a first and with a second valve arranged for determining corresponding flows of the cooling gas to be introduced, respectively, in the first and in the second cooling section. A pressure sensor is employed in order to determine the pressure in the cooling chamber, by controlling the fan in a feedback manner.

    摘要： An improved extruder apparatus is disclosed and which includes a cylindrical barrel having a feed end and a discharge end, the feed end having an inlet in fluid communication with a hopper. The extruder screw is mounted in the cylindrical barrel, and the screw has an outer surface having one or more helical flights mounted thereon. wherein the inlet end of the cylindrical barrel has a support frame mounted thereto, wherein an upper surface of the support frame is connected to a throat of a hopper, wherein an insert is mounted to the support frame and has a lower end which extends down into the cylindrical barrel, wherein the insert has an internal passageway having a first opening on the lower end and a second opening upstream of the screw for relieving the pressure.

    摘要： A closure for closing a bag and a die head and method for making the closure. The closure includes two closure members having support walls and mating interlocking profiles. The support walls are resilient and have self-retaining forms in vertical section including middle sections curving outwardly away from one another when mounted on a bag. Top portions of the support walls extend outwardly away from one another to form gripping panels when the closure is closed. A die head for forming a closure member includes a body that defines a slot including a support wall segment for forming the support wall of the closure member. The support wall segment includes first and second portions oriented transverse to one another and intersecting at a vertex. To form the closure member, polymer is extruded through the slot and quenched.
