A new Perspective of excellent care | Gujarat Paper Tubes & the other Sister Companies of the same group has been a pioneer in the manufacturing of Spiral Paper Tube and Parallel Paper Tubes for over 40 years in Ahmedabad. Such a cutting roller has multiple circular cutting blades arranged in the axial direction thereof, and these circular cutting blades rotate together with the cutting roller to form grooves in the paper material. The returning portion of the garniture belt 22 is guided by a number of guide rollers 24, and is wound around a drive drum 26 at a predetermined winding angle. an original surface profile. Figure 3 shows the main steps of typical paper manufacturing. Have you ever seen the television show How Its Made? Can you explain how ply angle is arrived. While you probably think a paper tube-based product is only suitable for dry goods, surprisingly I have found that this is not the case. The above-mentioned bobbin holder 12 has a built-in brake (not shown), and this brake imparts a predetermined tensile force to the paper material P. A groove forming device 28 is disposed on the feed path 14; the details of this groove forming device 28 are shown in. The present invention also provides a paper tube manufacturing method and a paper tube manufactured by the manufacturing method. The two main types of paper tubes and cores include spiral wound and convolute or parallel wound paper tubes. The paper tube is being directed into the cutting unit, and at the right time, all of the rotating knives will come in towards the paper . The paper ribbons are rewound into narrow rolls on rewinding stands. The web bending device can further include a press roller disposed upstream from the tube forming section, and the press roller presses the paper web against the garniture belt. Professionally drafted and regularly updated online templates. Electricity 3 Phase - 380 V. Dimensions for machine - 2600 x 1050 x 1550 (L x W x H) in mm. Step 3: Wind the piles. Some only make toilet paper rolls, while others only make wine bottle canistersand then there is everything in between. Meanwhile, the paper material P is introduced from the above-described feed path 14 onto the advancing portion of the garniture belt 22 and is lapped over the garniture belt 22. The fabric reinforced rubber belt also advances the tube forward along the mandrel.
