Autofeed hand screwdrivers and fixed screwing units represent the first step of assembly automation. They are simple and reliable systems where the screw or the nut is automatically fed into the driver collet head. The automatic down stroke, featured also by the manual system, reduces operator's fatigue increasing dramatically assembly rate and productivity. You can feed and tighten machine and self tapping screws, nuts, studs and any other threaded fasteners with or without washers. Multi-spindle tightening applications improve assembly results and increase productivity. Kolver creates custom designed multi-spindle equipment that can be configured in either vertical or horizontal orientations depending on the application and customer requirements. Designs may incorporate operator input or be fully automated. Spindles can be mounted and arranged to accommodate and match any bolt pattern using in-line, 90° angle or special offset drives. Kolver multi-spindle tightening systems allow for spindle synchronization, operator feedback and error proofing solutions.
