Abstract: Method and apparatus for winding wire on a double flanged spool by means of a single spooler wherein the wire is automatically carried from a feed roller toward the spindle by grasping the free end of an endless wire, guiding the grasped end in an orbital path about a spindle, until a portion remote from the wire is grasped by another means adjacent to the spindle and wire is then caused to be cast from the other grasping means over the end flange of the spool and onto the spool itself. Thereafter the wire is wound about the spool after which, the wire is automatically grasped and cut from the spool by the orbital means so as to restart a new cycle of winding.

Abstract: An improved trimmer section is provided for use in a sawmill, together with method and means for automatically selecting timbers and the like to be trimmed, and for automatically routing trimmed timbers to a preselected one of a plurality of different storage and loading points in the sawmill. In particular, the operator is required to select which of several stations is to receive each timber after it has been cut to a designated length. Thereupon, the timber is automatically transferred through several stages of mechanical manipulation to the designated station while, simultaneously therewith, another un-trimmed timber is promptly conducted to the trimming saws. Actuation of the entire operation is effected by merely selecting the station to receive the trimmed timber, since the cycle will repeat as long as there are timbers to be trimmed.
