A method of manufacturing curved wall portions of a heat insulating wall for a container having a curved surface, includes the steps of forming a block of heat insulating synthetic foam material with a contour embracing a section of a container surface to be insulated, cutting the block of synthetic foam material over the contour so as to form a curved blank, coating the curved blank with a baffle layer of the same contour, and finally cutting the coated blank along joining surfaces so as to produce a wall portion with final dimensions. An arrangement for manufacturing the wall portions includes a first unit provided with a cutting tool rotatable about a flexible web for cutting a block of heat insulating synthetic foam material over a contour embracing a section of a container surface to be insulated so as to form a curved blank, and a second unit including two pairs of band saws for finally cutting the curved blank coated with a baffle layer along joining surfaces so as to produce a wall portion with final dimensions. |
