Cloudy Paper formations,
Paper with unevenness in look-through.
Profile Control:
The uniform hydraulic flow from header and diffuser tube system makes almost zero cross deckle profile variations.
Air Bells:
Tiny circular thin spot in the paper. Also known as bubble marks or steam blisters.
Air Bubbles:
Light spots in a sheet caused by bubbles of air that form in the stock on a Fourdrinier wire (forming fabric) and are entrained in the stock as it cascades in trays and channels. The term also refers to bubbles of air formed in the coating operation and the defective imprint that is caused by the bubble bursting.
Pin Holes:
Imperfections in paper which appear as minute holes upon looking through the sheet. They originate from foreign particles, which are pressed through the sheet.
Wild Formation problems:
Paper sheet with uneven, random distribution of fibers, yielding a mottled appearance on look-through.

The Hema hydraulic headbox is a type of headbox used in paper mills that offers several advantages over other types of headboxes:
Uniformity of paper formation: The Hema headbox uses a hydraulic system to evenly distribute the pulp across the width of the paper machine. This results in a more uniform formation of the paper, which leads to better quality and consistency.
Improved control over paper properties: The Hema headbox allows for precise control over the flow of pulp and the pressure applied to it. This enables papermakers to adjust the paper properties such as basis weight, caliper, and surface smoothness according to their specific requirements.
Reduced paper breaks: The uniformity of paper formation achieved by the Hema headbox also leads to a reduction in paper breaks during the production process. This not only saves time and money but also improves the overall efficiency of the paper mill.
Lower energy consumption: The hydraulic system of the Hema headbox requires less energy compared to other types of headboxes, which leads to lower operating costs and a smaller carbon footprint.
Longer service life: The Hema headbox is designed to withstand the high pressures and abrasive materials encountered in paper production. This results in a longer service life compared to other types of headboxes, which means low downtime and maintenance costs
