Analysis of some important proper nouns:


Overfeed: It is an action process that provides a specific proportion of the required amount according to the requirements of the next step.

Specific ratio: There are positive, negative or zero, that is, positive overfeed, negative overfeed or zero overfeed.

Requisite Amount: which is expressed as speed, flow, quantity, quality, etc.

The requirements for the next step: depends on the purpose of the treatment to be achieved.

The amount of overfeeding: it is by the super-feeding mechanism through the data relationship between the front and back of the mechanism.

Measurement and Control Instrument: It is the necessary matcher.

1. The Hot Air Stenter setting machine needs more fabrics to be fixed on the needle board in advance in order to eliminate the longitudinal stretching amount of the fabric before the dyeing process and meet the requirements of customers.

For example, the feeding mechanism runs 120M per minute, and the needle plate of the fixed fabric travels 100M per minute so that the 100M position is squeezed into the 120M fabric (plus overfeed +20%), and then the high temperature is set, and the fabric is 100M after the lower machine. The amount of longitudinal stretching is eliminated. At the same time, increasing the needle plate distance will control the fabric width, eliminating the lateral shrinkage of the fabric pre-dye bleaching process. Conversely, if the only 95M fabric is fed, it will be stretched to 100M (negative overfeed - 5%). This is also the way sellers make money, so the buyer stipulates the vertical and horizontal shrinkage and the average weight (knit) to distribute the amount of money.

2, Spinning and winding and even weaving, will involve or adjust the amount of overfeeding, such as the spun yarn, the spinning should be over-feeding; the roving yarn process is negative overfeeding (feeding a few 100m cotton wool spun into tens of meters of yarn); (precision) winder (lower and constant winding density of the super-feeding control); weaving machine weft feeder (control yarn In particular, the tension of the elastic yarn ensures non-negative overfeeding).

3, Much continuous processing equipment (other industries) also often have such a mechanism, such as the tensioner of the dyeing machine is to coordinate the front and rear speed, to control the negative overfeed of the fabric transported by the front mechanism, the fabric will not be excessively stretched.
