FOCUS ON FOLDING
designed for a wide range of industries and are suitable for light-duty applications such as box and pan , panels , flashing etc . We recommend them for metalworking fabricators in the HVAC , roofing and sign-making industries ,” it said .
Hershey ’ s Metal Meister in Mattoon , Illinois ( USA ), is a family-owned business with a history of rollforming and machinery manufacturing . The company purchased the North-American patent rights to European folding manufacturer Variobend ’ s products and is the U . S . manufacturer of Variobend equipment . Its portfolio includes single / double folders , a double bender and a single bender .
It builds Variobend machines in the U . S . with SAE hydraulic lines , hoses and other components . In fact , all hydraulic components are sourced in the USA . The company is also a distributor for the Slinet automatic slitter lines built by the same company who designed the Variobend machines . It also has a sub-foundation insulation division known as Hitz Halter , a metal supply store ( Permanent Building Solutions ) and a roofing metal brand , Pemamag .
H . M . Transtech , s . r . o . is a privately owned Slovakian company with more than 25 years of experience in the production of sheetmetalworking machines .
Its production programme offers standard machines as well as machines with modern graphic CNC control systems . The production range includes manual folders up to a maximum length of 4m ; shears ; plate bending machines ; motorised and hydraulic shears ; motorised folding machines ; coil-processing / sheet lines and other special machines .
“ Our motorised folders are suitable for small-batch and mass production of simple open and closed profiles and boxed products . Motorised sheet metal folding machines are highly flexible in the transition to different types of products . The capacity of the motorised folding machines ranges from

1-8mm of thickness and length is in the range of 1-5m ,” said the company .
JORNS AG is a Swiss manufacturer of folders , double folders and accessories used for processing sheet metal . It celebrated its 50- year anniversary in 2023 . Its customers mainly work in roofing or architectural sheet metal . Products range from simple NC-controlled machines to sophisticated CNC-controlled sheet metal bending systems and a J-Bend app , functional on tablets and mobile phones ,
Jorns ’ dynamic positioning technology for folders . to support the management and production of sheet metal profiles .
“ The area in front of and behind the clamping tool of the Jorns JB bending machine offers above-average open space , letting users manufacture bending profiles extremely efficiently . The use of servo technology and the stop fingers that can be moved freely on the sides guarantee maximum precision and flexibility to bend parallel , tapered or overlapped profiles ,” it told ISMR .
The semi-automatic Jorns JB folder and fully automatic Jorns JDB double bending folder can be configured in lengths of 3.2 to 12.2 metres and boast bending capacities for sheet metal of up to 3mm .
“ The simultaneous bending of complex profiles poses no problem for the Jorns JDB double bending machine because multitasking is a given . The area behind the clamping tool , with a retraction of over 290mm for the bending tools , offers above-average open space . Users can then produce bending profiles without turning them around or over , with an array of possible profile variations . Several parallel , tapered or overlapped profiles can be bent simultaneously , an innovation that increases the speed of work ,” commented Jorns .
The use of servo technology , the automatic loading and unloading table as well as the individually driven clamping fingers enable precision and flexibility . Thanks to two bending tools , material handling has also been drastically reduced .
Jorns also offers dynamic positioning which allows the uniform closure of a hem over the entire length of the profile ; the pre-tension is programmed into the control system and lets the clamping arms exert more pressure in the middle of the profile , up to the maximum clamping pressure if needed . Thanks to the modular design of the machines , Jorns bending machines can also be retrofitted with
