Background technology
, it is necessary to carry out grabbing the processes such as cotton, shredding to cotton bag in textile mills；Subsequently also have blowing, combing, drafting, rove,
The working procedures such as spun yarn, winder., it is necessary to which spun yarn is made into base by knitting equipment or weaving equipment after by fiber yarn forming
Cloth.And subsequently also have each process that final finishing is carried out to fabric, such as dye, press sizing.Finished fabric is used for again afterwards
Cut, the various commodity such as clothes are made.In these processes, it can use and arrive substantial amounts of machinery equipment, and these machines
In equipment, some components are elastomer, it is necessary to apply predetermined pressure to elastomer in the installation process of elastomer, so that
Elastomer is in compressive state, so as to produce bounce to component in contact.For example, in some fields, it is necessary to using
The elastomers such as spring, and predetermined pressure is applied to elastomer and is fixed in some space.But due to elastomer itself
It cannot indicate pressure applied size, it is therefore desirable to by close apparatus measures pressure applied, thereby determine that elastomer
Bounce caused by upper.However, by using the limitation such as space or environment, the instrument for measuring pressure has larger volume,
There can be the drawbacks such as inconvenience measurement in actual use.For example, in some narrow space install one need to produce it is predetermined
The elastomer of bounce, this narrow space cannot use the apparatus measures of measurement pressure.So at this time, how accurately to bullet
Property body apply predetermined pressure, reformed into a stubborn problem.Meanwhile often measuring instrument is relatively valuable, in operation also
Easily lose, cause property loss.
