Claim:
A finished product receiving rack of the type used in a corrugated metal sheet member fabrication system and having two rows of rollers pivotally mounted on a rack body thereof and movable between an operative position for carrying finished products from the corrugated metal sheet member fabrication system and a non-operative position for letting carried finished products fall from the rack body, said corrugated metal sheet member fabrication system comprising a material feeder adapted to feed a metal sheet material, a roller ramming unit adapted to receive said metal sheet material from said material feeder and to roller ram said metal sheet material into a corrugated form, a cutting unit adapted to cut said corrugated form into corrugated metal sheet members subject to a desired size, the finished product receiving rack comprising: two guardrails arranged in parallel along the length of said rack body and together defining a horizontal plane, wherein the guardrails are configured to be selectively translated horizontally towards and away from each other so as to vary a horizontal gap therebetween; two transmission shafts arranged in parallel along the length of said rack body; two sets of steering gears arranged on said rack body at two opposite lateral sides along the length of said rack body corresponding to said rollers and respectively coupled to said transmission shafts; two sets of guide screws respectively coupled to said steering gears and said guardrails and rotatable by said steering gears forwards/backwards to move said guardrails relative to each other so as to vary the horizontal gap between the guardrails; and two motors fixedly mounted on said rack at two sides and adapted to rotate said steering gears.
