Since 1989, we've been offering our Made In USA Vacuum Bridge Guides.   All machines

are manufactured with a maximum 98" width...have manufactured for 108" corrugators.

CM-1:  Center mounted machine with no lateral adjustment.

 

LA-1:  Each chamber is mounted on linear bearings with a hand wheel for each

station's manual alignment.

 

LA-2:  Same as LA-1, except with a motor to position each chamber. Controls

at entrance to hot plate section and at the slitter scorer. Each chamber has a

display to display position relative to center line of machine to use as a

reference for the operator.

Can be installed over a weekend.

Lead time now down to 12 weeks!

Vacuum Bridge Guide Features:

Even tension across full width of web provides many benefits over conventional bridge guiding and

tensioning devices. Improved paper quality is accomplished by providing more even heat transfer

at the pre-heaters and more even glue application at the glue machine. The even tension across

the full width provides even contact with pre-heaters and glue applicator rolls.

The full width tension and improved guides provide improved warp control. Web walk is also

reduced, which will reduce trim requirements.

Improvements in operator control releases the double backer operator to do other more important

duties during paper width changes. Next order is preset and order change is accomplished with

one button press.

Very simple and open design provides a very reliable machine with virtually no down time. All surfaces exposed to paper contact

are hard chrome plated to provide superior life and reliability.

Even Tension

Chamber Features

Machine consists of two chambers equipped with a 5HP blower to provide vacuum. Vacuum is

controlled by means of a variable speed controller for each motor. Percent of vacuum is displayed

on the touch screen operator interface.

Each guide is a hard chrome plated steel plate 1/4" thick. The widths are controlled using one

screw with opposite threads on each end to position guides relative to the centerline of the

machine.

The motor that drives the screw for the guides also drives a screw for each damper inside of each

chamber. This opens and closes the size of the chamber to match the width of the paper. this

provides full width tension without allowing any vacuum to escape.

Guides are mounted on linear bearings and the nut is made of brass. No lubrication is required,

any used will only attach dust and reduce life of brass nuts. The internal dampers are made of UHMW plastic with a brass nut

insert identical to the ones used on the guides. The motors for the positioning of the guides are two speed motors. Full speed

until within a preset range, then the guides "creep" to the final position. Guides always come to a stop from the close position to

eliminate any backlash.

The paper is fed over one roller, below the vacuum plate, then over the exit roller. The lack of unnecessary rollers reduces the

chance for any misalignment which causes tracking problems.

If machine equipped with motorized shifting (LA-2) Each chamber is mounted onto linear bearings and a screw is used to position

the chambers. The motor used is a brake motor with a high reduction inline gearbox. The chamber can be positioned

approximately 2 1/2" off center in each direction for alignment, and also allows alignment of varying web widths.
