laminators

🤔 How it works ……..

How do laminators work?

A laminator machine typically uses a combination of heat, pressure and an internal roller mechanism to apply a thin plastic cover to paper documents or other items, In the most common scenario, the paperwork in question is fed into the laminating machine one page at a time, sandwiched in loose plastic sheets or lamination pouches.

In the case of most modern pouch laminators, the plastic cover placed around the document being fed into the machine is pre-coated with a special sort of extruded adhesive on all of its inside surfaces.
As the pouch is heated under pressure from the machine’s rollers, it helps to bond the two sides of the pouch tightly together across the front and back surfaces, forming a protective cover and seal around all four sides.

Some higher-end laminating machines will allow the user to adjust settings for temperature and feed-through speeds, which can make the job more efficient and effective when dealing with heavier duty pouches or larger work pieces.
In addition, some machines have the ability to reverse-feed documents that have become misaligned, often using special sensors that can detect misfeeds and perform this reversal function automatically.

😳Why❓❓❓

Why we will not feel that we are rotating while earth rotates? 🌎🌍🌏

We can’t feel Earth rotating because we’re all moving with it, at the same constant speed.
Earth spins on its axis once in every 24-hour day. It’s because you and everything else – including Earth’s oceans and atmosphere – are spinning along with the Earth at the same constant speed.

If the Earth stopped spinning suddenly , the atmosphere would still be in motion with the Earth’s original 1100 mile per hour rotation speed at the equator. This means rocks, topsoil, trees, buildings and so on, would be swept away into the atmosphere.

For simple understanding: Think of being on an aeroplane when it’s smoothly travelling at a constant speed and constant altitude. You’ve unbuckled your seatbelt to go on a walk down the aisle, but you can’t feel the movement of the plane. The reason is simple: you, the plane, and everything else inside it is travelling at the same speed. In order to perceive the movement of the plane, you have to glance at the clouds outside.

It’s the same with Earth’s rotation – our planet completes a full turn around its axis every 23 hours and 56 minutes, spinning incessantly at an almost entirely constant rate.
