Shirt thread assembly for use in e.g. press machine, has screw matched with variable screw, where screw is provided with external diameter and root diameters of other two screws are remained constant

NOVELTY – The assembly has a screw matched with a variable screw (8), where the screw is provided with external diameter. Root diameters of other two screws are remained constant. External diameter of a thread is greater than diameter of an entrance region of a material and lower than diameter of region of material output. Internal diameter of a shirt (2) is larger than that of region of a material inlet and lower than that of the region of the material output, where space is formed between a top thread and a jacket. A constant internal diameter (6), a shaft (1), a screw body (3) and a material inlet (7) are provided. USE – Shirt thread assembly for use in a press machine, an injection machine and an extruder machine (all claimed). ADVANTAGE – The assembly adjusts distance between the thread and the shirt so as to set a parameter of a press machine, thus increasing service life of the thread and the shirt, and increasing versatility of the screw and the shirt. DESCRIPTION OF DRAWING(S) – The drawing shows a schematic view of a shirt thread assembly. Shaft (1) Shirt (2) Screw body (3) Constant internal diameter (6) Material inlet (7) Variable screw (8)
