Abstract

A device for stiffening workpieces of paper includes elements that provide the workpieces with an undulated profile. The elements may be in the form of freely rotatable disks or belts that revolve around freely rotatable rollers. Respective sections of the disks or belts which come in contact with the workpieces extend through a common central plane in such a way that they provide the workpieces with an undulated profile. In order to prevent the profiling elements from laterally displacing the workpieces, a conveyor is provided which clamps the workpieces between respective conveyor sections.

Description

Enhancing is by the equipment of the flat piece of paper or similar material system

The present invention relates to a kind of in bag production is used to strengthen by the flat piece of paper or the similar material system especially equipment of flexible tube section.

For example, from the fragment that roll web scales off,, they further process for being concentrated or do, stacking or continue to carry in addition, in this case, because the flexibility of the scraps of paper or very do not scrape, so stack exactly in the position or cause difficulty when continuing conveying.

In order to make pouch, roll web is pulled out from reel, usually multilayer is merged, the area bonded of sealing and will overlapping mutually with overlapping mutually by the side forms little flexible pipe together then, then little flexible pipe is cut into flexible tube section for further being processed into pouch, flexible tube section at a high speed with overlapping each other throwing or be stacked on the sheet conveyer belt.For the flexible tube section that prevents to scale off from the flexible pipe bar when for example throwing them on the sheet conveyer belt owing to they very do not scrape and/or flexibility is got the position of inclination and inaccurately alignment each other, known way is to make these flexible tube sections by a wheel that works, these take turns on flexible tube section make corrugated.Because this corrugated flexible tube section that strengthened, so they no longer can the crooked or upset around its transversal line.But, basically be located at the briquetting roller of workpiece longitudinal centre line both sides, cause uncontrolledly the material of flexible tube section side being drawn in, can not guarantee which layback to go into material in this case from, like this, for example can carry out the workpiece side on back to back sheet conveyer belt does not again have the flakey of accurately alignment to stack each other.

Therefore the objective of the invention is, the equipment of the described type of a kind of preface is provided, the edge of its assurance workpiece is stacked with flushing, and these workpiece are made corrugated profile by the former that makes their enhancings.
