冻虾怎么做好吃又简单摘要：Traversing mechanism for u in any type of machine in which part of the machine is required to reciprocate between two predetermined limits of travel. The mechanism includes a carriage which is attachable to that machine part, and an endless belt which, in operation, is continuously driven in one direction and has two parallel runs located on opposite sides of the carriage. A rotatable coupling wheel is mounted on the carriage and has an odd number of radially projecting lobes arranged around its periphery so that in one rotational position of the wheel one lobe engages one run of the belt, and in another rotational position of the wheel another lobe engages the other run of the belt. The arrangement is such that in each rotational position of the wheel there is only one lobe in full engagement with the belt. Stops are provided at the extremities of the carriage travel, and each time a stop is engaged the resulting interaction between the belt and the wheel caus the wheel to rotate to adopt a new position such that the drive imparted to the carriage alternates between the two belt runs. A sliding escapement is provided to restrain the wheel against inadvertant movement from an operative position, and that escapement is moved to relea the wheel each time a stop is engaged.
