Abstract: The finishing machine of the present invention includes a drive assembly for moving a coated object longitudinally across a base at a predetermined speed and a finishing assembly connected to the base to contact at least a portion of the coating as the object moves across the base to raise the temperature of the coating to about its thermoplastic range for a predetermined time and to finish the coating during that time to a desired uniform finish. The finishing assembly includes a revolving brush having nylon bristles impregnated with a suitable abrasive. For moldings, the brush is mounted to a frame which is adjustable above the base to vary the height of the brush above the base and its angle with respect to the base. Edge finishing brushes may also be included on the base for finishing edges of the object as it passes through the machine. The method and apparatus are suitable for small objects, such as moldings, or large objects, such as doors.

Abstract: In a method for increasing the cover of textile fabrics yarns are used, at least part of which exhibit potential fiber-spreading properties, which can be activated by removing from said yarns, processed into a fabric, the adhesive used for the fiber bonding in the yarn by means of a suitable solvent. The selected number of warp and weft threads per unit area is so small that on the one hand an optimal fiber spreading is obtainable, but on the other hand, after activation of the potential fiber-spreading properties, sufficient cohesion of the fibers in the fabric is retained for further processing of the fabric. After obtaining the desired fiber spreading the fiber bonding, partially lost through the activation, is at least partially restored.

Abstract: A napped fabric is treated to bond the nap fibers together while leaving the nap structure largely open and porous.

Abstract: The present invention provides a method for manufacturing a fabric-type artificial leather, wherein a nonwoven fabric is formed by using a dry method to join together hydrophobic fibers. The fabric so formed is densified by needling and the activation of shrinking forces. It is then impregnated with a mixture of a heat sensitive elastomeric bonding agent, powdered barium sulfate and a compound that reacts with acid to form a gas. The impregnated fabric is then exposed to a heated, acidified liquid which triggers coagulation of the bonding agent and liberates a gas formed by reaction of the acid and acid-reactive compound. The resulting solidified fabric is then washed, dried and ground-over on at least one side to produce a nap. Finally, the fabric is intensively fulled.

Abstract: A magnetic imaging system is disclosed wherein an optical image is first reduced to a graphic image by employing a magnetizable marking material followed by magnetization of the graphic image and transfer of the imagewise pattern of magnetization to a magnetic substrate to provide a latent magnetic image. The latent magnetic image is utilized for the purpose of image duplicating by successive development and transfer steps or for electronic transmission of information. Improved latent magnetic images are provided by retoning the graphic image after magnetization and further magnetizing the retoned graphic image from which the latent image is produced. Also, polishing the redeveloped graphic image further improves the quality of the latent image.
