Patent number: 5176777Abstract: In a process for covering an object by means of at least one flexible piece, a fluidized bed of particles (8) is covered by a flexible cloth (10), the flexible covering piece (12) is placed above said cloth, the object (13, 14) is placed above said cloth, pressure is applied to said object, deforming the flexible sheet and immersing the object in the fluidized bed until a mating imprint is formed in the latter. The covering can be effected by gluing, in particular with a previously applied heat-activated adhesive in which case the fluidized bed is obtained by means of a current of hot air at a temperature above the activation temperature of the adhesive. The process is particularly suitable for assembling and mounting seat covers. Also described is a device for implementing the process.Type: GrantFiled: January 14, 1991Date of Patent: January 5, 1993Inventor: Christian Guilhem
