Abstract (en)
A roughened cleaning sponge, particularly for easily scratched surfaces, such as stainless steel surfaces, surfaces coated with thin layers of a plastic material, motor vehicle windshields, and the like, which comprises a core (2) of a sponge-like materiale covered with an outer roughening fabric (3). Both the core (2) of a sponge-like materiale and the roughening fabric (3), the latter being a knit tubing, are formed form a thermoplastic plastics. The crosswise seams are pressure heat sealed to define a stiff heat sealed band (4) having scraping side and corner portions (4a). A reliable and durable envelope is thus provided for the sponge-like core (2). Manufacturing begins with the formation of a basic blank (6) of some length from which individual sponges (1) are fabricated by heat sealing and severing along the heat sealed end bands (4) thereof.
