This article describes a simple, low-cost method of attaching a toothed timing belt to a printer carrier in a printer utilizing a belt escapement system. In this arrangement, a timing belt 10 is attached to a carrier by interlacing the belt between a curved formed rack 11 and two side tabs 12 and 13. The rack 11 and tabs 12 and 13 are stamped from aluminum and formed in a progressive die. The belt 10 can be laterally installed between the rack and tabs, and then tension applied. The applied tension T causes positive engagement between the belt and rack, and, because the exit angle of the rack is equal to the pressure angle of the timing belt tooth profile, a non-slip attachment is provided. Some advantages follow.
