Being a regular consumable item for a spinning mill, the process is generally considered very simple. However, tremendous technical skill is required in the making of paper cones & paper tubes. Following is a summary of the process involved in the manufacturing of paper cones.
The first step involves punching of tubes and cones. The paperboard is cut according to the size and conicity required by the customers.
Grinding of edges is done and then the paste is applied on the paper cones.
After grinding, winding is done at the spindles of the same conicity.
After winding drying takes place at controlled temperatures.
By the process of velveting, rough finishing is given by a 152 mm emery belt.
After velveting, the base of paper cones is cut. Bottom cuts are given as per customers' request, in the form of V cut, U-cut, Y-cut & moon cut etc.
A small v-shaped indentation is made at the bottom of cones. This process is called nothing.
The paper cones & tubes are weighed before dispatching. The weighing range of ± 2 to 3 gms is maintained at our plant.
After the weighing process is over, sorting of cones is undertaken. Non- conforming products are rejected at this stage.
» Pre-despatch Inspection:
Before the final dispatch to customers is made, stringent inspection is carried out. At this stage, 5% samples are tested in order to make ourselves very much confident of our quality.
Paper cones/tubes are packed in varied sizes according to specifications provided by the customer.
