Equipment Included: 1. Slitting Machine: It is used to slit the paper to the required width. In this machine, paper roll having 40" width and 36" diameter can be loaded and slitted. There will be 12 Sets of Top and cutters in this machine with adjustable arrangement. After slitting, Slitted reels will be rewound on two rewinding shaft. The Tension of rewinding can be adjusted by means of mechanical clutches. Master roll can also be adjusted in position and tension. Minimum 3 tons can be slit in one shift. Minimum width of slitting is 40 mm and maximum will be as per requirement. 2. Reel Holding Stand: Reel Holding stand is used to hold and feed the paper properly into Glue Cascade system. The number of Stations for paper loading will be 10. Paper from 35 mm to 150 mm width can be loaded in this stand. It is made of MS angles and flats. It has bottom rollers to adjust to any position during operation. 3. Cascade Gluing System: It is used to transfer the Glue from Glue tank to paper layers properly. In this system, there will be a Glue tank having stainless steel inner Jacket and MS outer jacket. Between these two jackets water will be there which will be heated to boil the Glue by means of electric heaters, if necessary. Glue will be pumped to Paper layers by Gear pump of capacity 110 litres per hour. Paper tension arrangement, Glue supply system and glue scrapper system to remove excess glue provided. 4a. Pre-Forming Machine: In this system, the paper layers are fed into rotating Rubber rollers and formed to the required thickness. Outer layer having low GSM (paper thickness) and low Glue Value is fed along with these papers by means of extra glue arrangement. In this machine, the required width and thickness is obtained. 4b. Forming machine: After pre-forming , the papers are fed into forming machine which has three stations with big angular female and male rollers operated pneumatically. As the paper is fed through the machine, the angle is formed stage by stage and then it is passed to the shearing system Rollers are driven by a 5 HP DC motor with control. The speed can be adjusted by means of DC Drive. 5. On-Line Guillotine Shear Cutting Machine: The formed edge protector is passed to the online Guillotine Shear. It cuts the edge protector to the required length. Shear is operated by a pneumatic cylinder which is actuated by an electric switch / sensor. 6. Fine Cutting and Wrap Around Punching Machine: This recuts the edge protector to the required length of small pieces and also does angle cutting if required so that the edge protected can be folded to make round shape In this system, a die is fitted into a 10 Ton Power press. 7. Compressor with 7.5 HP Motor: Reciprocating Air Compressor with delivering capacity of 14.5 Cfm @ 12kgf/cm2 maximum working pressure with 7.5 HP Motor & Starter mounted on 220 Lit Air Receiver with std accessories |

Process of manufacturing the Angle Board 1. Load the paper strips as per the size of paper angle required on the reel stand 2. Paper mounted on the roller and rods will arrive at the Glue Stand 3. Paper Strip Gumming takes place at the Glue Stand by spraying adhesive on the strips with a pump 4. Excess glue from the paper strips is removed by scraping knives 5.The excess glue goes back into the gluing tank 6. Paper strips are pasted on each other at the Parchment Stand 7. The gummed paper strips are then passed through the rollers to give them the angle 8. There are two heaters between the pressing rollers to give strength to the angle board 9. The Angle Board is cut at the desired length by the Auto Cutter 10. Optional Operation: Power Press is used to cut slots on the Angle Board for use on round articles like drums |
