Abstract (en)
[origin: EP0120828A2] A method and an apparatus for the manufacture of heat-exchanger rolls (10). The roll (10) consists of two webs (12, 14) of material which are wound together in superposed relationship. One (12) of the webs is corrugated and formed with protrusions/dents at the crests and bottoms of the corrugations. The second web (14) is provided with lengthwise ribs having the same configuration as the protrusion/dents. When the webs (12, 14) are wound into a roll (10) a radial pressure is exerted on the wheel (10) in order to press the ribs efficiently into the protrusions/dents and to achieve efficient and safe interconnection of the various winding turns making up the roll (10). To impart a tension in said webs (12, 14) a retarding (braking) force is applied thereon during the winding-on of the webs. The invention also comprises an apparatus for performing the method, the pressure and braking force on said webs being exerted by a pressure roller (56).
