What Is a Paper Jogger?
A paper jogger is a device commonly used in the printing and bookbinding industries to align sheets of paper before they undergo cutting or collating.
In settings where large volumes of paper are processed, the sheets often emerge from printers with static cling and stickiness, leading to clumps. A paper jogger first separates these sheets by introducing air between them. Subsequently, through vibration, the sheets are realigned and excess air is expelled, readying them for precise cutting or binding.
What was once a skilled manual task has largely been automated by paper joggers. These machines, also known as ‘knocking up machines,’ are specifically engineered to remove air and align the corners of paper stacks. Furthermore, the term ‘Paper Jogger’ includes not just standalone machines but also units integrated into printing machines. These integrated devices align printed sheets from various directions, ensuring neatly stacked output.
