Introduced in France in 1930 by Mr. Paul BAP, founder of Profilafroid, the steel profiles made from steel coils, also called strips in rolls, were already developed in other countries. Especially in the United States, England and Germany. nitially realized on a cold drawing bench, the process has been completely transformed by the use of machines with roller trains, called profileuse, allowing a continuous production and much faster than that of the drawing bench.Read more -
Sometimes it’s good to know when to ask for help. This is especially true when making decisions for a large business. At times, metal manufacturers hit a crossroads when trying to decide the best way to complete a project. Time and money are often two things at the front of a decision-maker’s mind, and a hyperfocus on these savings can lead to costly decisions.Read more -
All of these are crucial in the continued production of metal fabrication worldwide. Without these impressive machines and the continued improvements in technology and machinery in the metal roll forming industry, there are so many industries that would quickly become unsustainable.Metal roll forming plays a part in many everyday items that we use without perhaps even considering how they were created. They also are essential for much larger scale projects such as building construction and car manufacturing. Some items are mass-produced for businesses as well as consumers. Others are incredibly specialized and only cater to a particular market.Read more -
Roll forming machinery is a boon for both the quality and efficiency of metal fabrication. It allows for repeatable consistency within a product run, as well as versatility in design configurations and materials for metal parts. With wide-ranging applications from appliances and furniture to telecommunications and supports or frames for construction, this equipment produces large volumes of formed metal parts quickly, accurately, and affordably through consecutive bending stages.Read more -
Stretch forming is a type of metalworking most commonly used in aerospace applications. During the metal stretch forming process (also known as ‘wrap forming’), metal sheets or extrusions are stretched to exceed their inherent elastic limit and formed around contoured dies to create the desired shape. This “stretching” results in an increased material yield strength and a stronger finished part. Since stretch forming machines maintain constant tension of the metal throughout the process, they minimize imperfections and wrinkles.Read more -
What is a roll forming machine? Roll form machines are designed to make sheet metal into straight formed shapes. The roll forming process takes a continuous flat sheet of metal and power feeds it through a successive series of Hardened Steel Rollers, which station by station shape the metal into a finished shape as it passes through them. This method allows for rapid shaping of sheet metal into many shapes. From simple corrugations to completely closed long shapes. The metal is gradually shaped preventing too much stress on a a particular area. Because the shaping happens by drawing, in many cases, coiled sheet metal through the machinery, high volume production is possible.Read more -

When you hear the word “laser,” what do you think of? For many people, lasers bring to mind images of Star Wars lightsabers and sci-fi movies. While lasers often feature in popular culture, many industries use laser technology as part of their manufacturing processes to cut and engrave materials.Read more -
What is a roll forming machine? Roll forming machine is a manufacturing equipment used to shape sheet metal or coiled material into a specific profile or shape by passing it through a series of rollers, also known as roll tooling.Read more -

longway’ core business is machine control and production management for roll forming industries. As such, length control is a primary focus, so we wanted to produce a series of articles on issues that can cause length variance– where problems come from, and how to eliminate them. Once we got past encoder issues (which are common across all machine types), we wanted to tackle length control based on machine application – non-stop vs. stopping, servo control vs. non-servo control.Read more
