Each Rollformer is specially designed to match the part profile, material to be formed, and overall production criteria. Many companies tend to overlook automation for rollforming due to the wide range of lengths, punch patterns and end-notching configurations required in their product. Our Engineers are solving these and many other production problems every day. Vast and dramatic changes and improvements have been made in all fields of electronics, including types of Feeds and Index Drives along with major developments in Hydraulic and Pneumatic Controls. The options are almost endless to any company aggressive enough to understand and utilize what’s available today for the equipment of tomorrow. The Rollformer can be Pre-Tooled with two (2) sets of tooling (side-by-side) to form two (2) independent part sections.  Each section will have its own, separate Cutoff and Form Press. The entire unit will be laterally shifted inline with the Coil Strip Feed when changing products. We build systems to increase productivity, minimize inventory and handling. Systems are tailored to eliminate or minimize changeover of setup time. Quality systems at a price you can afford.

The Spindle Housings are precision ground and machined to exact tolerances. Spindle Shafts are retained within quality machined Spindle Housings using Heavy Duty Timken style Roller Thrust Bearings. The Shafts are close tolerance precision ground to match the Hardened and Polished Tool Steel Roller Dies.

This total On-Time Production System allows you to run individual parts with a wide variety of lengths and patterns, eliminating setups, downtime and/or scrap loss.

In our designs we try to understand the overall needs and requirements of our customers. Over the years we have developed and incorporated features that reduce setup and downtime, allowing greater flexibility in material and part variations, with greater accuracy and dependability. This system is just one example of the flexibility we offer. The Rollform Tooling is variable from a simple Hand Wheel Lead Screw adjustment and requires less than a minute to change from one part width to another.

InboardInboard Application Forming Rolls mounted on Inboard Spindles between the Bearing Housings. Rollforming is the art of progressively forming metal to produce a wide variety of profiles and configurations. The part size, material, and profile determine the Roll & Shaft size, number of form stations required, vertical & horizontal centers, roll spacing, and horsepower required. Improper Rollformer sizing can cause excessive stretching, bow, twist, ripples, and oil canning of the formed part.
A Rollformer can be tooled with Inboard Tooling (Rolls positioned between the Roll Shaft Spindle Bearings) or Outboard Tooling (Rolls mounted on external extended Roll Spindles). Whenever possible, part profiles should be run inboard. Outboard applications should be used primarily for forming the edges of the metal on wide sheets. BASIC ROLLFORMERS PAGE 2 OUTBOARD APPLICATIONOutboard Application Forming Rolls mounted on Outboard Extended Spindle Shafts that overhang from the Spindle Housing. Used primarily for edge form applications on wide sheets but can also form other profiles.

The Rollformer can be pre-tooled with two (2) edge form applications outboard and two (2) inboard profiles pre-tooled side-by side. Materials can be 26 Ga. parts on one set and 16 Ga. on the other with a setup or Roll adjustment. BASIC ROLLFORMERS PAGE 3PRE-NOTCHED STRIP FEED Rollforming a pre-notched strip feed. Rollformer indexes (starts/stops) and sequences notched strip for the cutoff.
Basic Rollformer Inboard Tooling Our systems can be designed in a wide range of Pre-Cut and Post Cutoff applications. We can pre-tool one (1) to four (4) sections in the same system depending on production rate and volume and versatility required.

Systems can be designed using a combination of Servo Index Feeds and Individual Hydraulic Press/Dies with a wide variety of pre-tooled Punch and Notch Dies sequenced with a Programmable Controller. It virtually eliminates all the setup previously required to produce parts. BASIC ROLLFORMERS PAGE 4 CONTROL PANEL
BASIC ROLLFORMERS PAGE 4 ON-TIME PRODUCTION SYSTEM This total On-Time Production System allows you to run individual parts with a wide variety of lengths and patterns, eliminating setups, downtime and/or scrap loss.

The Pre-Notch and Punch will gag the Presses and sequence the strip with the Programmable Microprocess Controller for an infinite variety of hole patterns, spacing and part lengths.

The Programmable Feed and Pre-Tooled Dies eliminate setups. The Controller is pre-programmed for over 100 different combinations and requires just simple part number and quantity inputs to produce a wide variety of pattern configurations. New parts can be entered directly from the user-friendly keyboard with simple data entries. This eliminates extensive programming and cost to add or change parts. It also allows the company to run the parts as needed and eliminate extensive inventory and part storage.

Programmable Rollfeed to pre-notch and punch down both edge of the strip. Variable Die Bed provides for a wide variety of strip widths. pre-notched / punched strip feeds directly into the Rollformer. BASIC ROLLFORMERS PAGE 4 HYDRAULIC PUNCHES
BASIC ROLLFORMERS PAGE 5 ON-TIME PRODUCTION The latest concepts in On-Time Production Systems. This type of system eliminates all the setup and inventory problems. It also can incorporate an Inline Endformer Cutoff Press directly after the Rollformer that eliminates a secondary endform operation and setup. It’s our goal to supply our customer with the best, most complete systems available and to solve as many of your production problems as economically feasible. Our systems show a wide variety of features combined for maximum production and minimum downtime for setup and changeover.
