Quietly fluid, exists small " vortex " on the top in space, and these " vortexs " can play and sliding friction is become rolling rub
Wipe, and stop the high-velocity fluid outside pit groove to enter the effect in pit trench interiors space.
Matrixes for embossing is tilting, and glass fibre cuts into 25.4～50.8mm and vertically descends slowly and lightly under matrixes for embossing surface relies on inclination gravity
Sliding, utilize the inner wall surface of the substrate of stainless steel substrate group, the glass fibre allowing rolling cut leave reduces contact surface, the most also reduces
Absorption affinity；Being contacted with salient point, pit groove has the effect of air cushion.
Glass fibre has electrostatic when feeding, has also produced electrostatic during rolling cut, and the two merges electrostatic 1-5kv；Stainless steel watch
Face embossing so that there is pit on surface, in glass fibre rolling cut process, the glass fibre of whereabouts just produces one air-flow, and surface is recessed
Hole just play positice ground effect, glass fibre on irregular corrosion resistant plate without or seldom have Electrostatic Absorption.

B=is sometimes how sometimes few, and C=has or sometimes a lot, and D=is the most a lot)
The lateral separation of table 1 decorative pattern, longitudinally spaced and wave height or ripple's depth and glass fibre degree of absorption experimental data
As it can be seen from table 1 under equal working condition, cut off the glass fibre frictional force that embossed surface glides that descends slowly and lightly less.
Embodiment 1 and the glass fibre of embodiment 4 in the present invention without absorption or seldom adsorb, and are in tolerance interval, embodiment
5 or seldom adsorb, growth over time without absorption at production run early stage glass fibre, also do not have the phenomenon of putty；
Comparative example is how sometimes few when glass fibre is adsorbed with at the beginning, and putty phenomenon occurs soon.

Ringing, on substrate inwall, decorative pattern protuberances or the decorative pattern recess of regular several composition decorative patterns that are staggered can effectively solve glass
The putty problem occurred in glass fiber production process, minimizing electrostatic adsorption force is main cause, because the glass opposing straight cut off,
If bucket face is plane, the most whole carries positive electrostatic glass to be close on headwall, it is not easy to because of gravity landing, if bucket face is corrugated surface,
Only several points that glass with positive electrostatic contacts with bucket, according to electric field force formula: F=kQ1*Q2/r^2, this power will be with two
The increase of electric charge distance, is greatly decreased interaction force, so the suction of glass and hopper is greatly decreased；Secondly, between decorative pattern protuberance
Pit groove or the convection action of the internal secondary vortices of decorative pattern recess be the Another reason of groove drag reduction.Rustless steel matrixes for embossing table
Drag-reduction effect preferable Another reason in face is to be full of the quiet fluid of low speed in the pit groove between decorative pattern protuberance or decorative pattern recess,
Existing small " vortex " on the top in space, these " vortexs " can play and sliding friction becomes rolling friction, and stops
High-velocity fluid outside pit groove enters the effect in pit trench interiors space.Therefore, in the substrate of described stainless steel substrate group
