This glue applicator is of diagonal arrangement structure, making up by a pair of applicator rolls arranging by declining 30 degree in horizontal direction. Sheet of paper licked up from drying cylinder group enters glue applicating channel made up by two applicator rolls to conduct after sizing, then entering next group of drying cylinders for drying. One of the two rolls is chromeplating roll, another is rubber roll. Chromeplating roll is fixed. Rubber roll is pneumatic. Hyperbolic pneumatic tyre apparatus single point transmission and double point transmission are adopted(This glue applicator does not include transmission apparatus).

Glue applicator is equipment supplied by complete machine. According to arranged transmission position, it can be divied into two kinds of arrangement forms of left handed glue applicator. Facing paper coming out direction, the one with transmission at right side is right handed glue applicator. The one with transmission at left side is left handed glue applicator. Our factory possesses the following specification and series: 400, 450, 550, 650, 910 etc.

It has two arrangements, i.e. left-hand machine and right-hand machine, please choose one type when ordering. Facing paper out direction of calender machine, whose mechanic drive is at its right side is right hand machine; whose mechanic drive is at its left side is left hand machine.When choosing,user should make it direction in accordance with that of its matched paper machine .The electric driving system of size press is uniformly configurated in the paper machine,this machine is only configurated mechanically.

Installation of size press

1. If the size press is assembled into the complete machine to leave the factory,it must be leveled up and put properly to avoid deformation.

2. On the foundation plate face,with the the top sizing roll direction of size press as the standard,make size press lift into the foundation plate face and place it in position,use plumb line methods to check its parallelism, visual measurement demands no error,then loacte and fix it well.

3. Use levels to check the parallelism on both ends of top sizing roll.

4. Adjust lower sizing roll to be parallel with top sizing roll,this a must,adopt the plumb line methods to measure it, visual measurement demands no error, tension mechanism should be adjusted neatly,after installation and correction,make the top sizing roll disconnect with lower sizing roll.

5. Install glue-obstruction device,make in-glue pipe and overflow pipe connect.

6. Use paper carrying roll to check parallelism,and to be parallel with top sizing roll.Doctor is installed according to the angle required by drawing,blade and roll surface should evenly dovetailed into each other,use euphotic methods and proof stick to check it,the 0.03mm proof stick should not be put into the gap,the closed length should exceed 95% of the whole length of doctor,move neatly,no blocked phenomenon.

Test run of size press

Installation of size press should be inspected completely to meet up to installation quality.On condition that the satisfaction of requirements can be guranteed ,zero-load test run can be started from low speed to high speed .The proper preparations ,operation procedure and matters needing attention of test run can be referred to test run of corollary paper machine.
