1. Assembly apparatus for securing toothed connector plates to sides of wood members such as 2×
- 4s comprising vertical axis longitudinally fixed side roller means for progressively pressing said connector plates with teeth placed against said wood members ahead of said roller means into wood penetrating assembled relation as they pass said roller means, and means for driving said wood members in required relation together with said connector plates past said side roller means.

Abstract
Assembly apparatus for simultaneously rolling opposed toothed metal connector plates onto both sides of horizontal wood 2×4'"'"'s or like structural members. The apparatus is applied to assemble trusses wherein a prefabricated wood frame of chords with end and intermediate spacers is fed between parallel vertical axis powered rollers with V-webs manually applied to each side ahead of and as the frame is compressively driven through. Similar apparatus is employed to splice the ends of wood chords for use in trusses or otherwise.

- 22. A production method for assembling wood members connected by stamped sheet metal elements having toothed extremities fixedly penetrating said wood members comprising the steps of prepositioning said wood members in assembly relation, positioning said elements on respective horizontally spaced sides of said wood members in required relation to each other, driving and guiding said wood members along a horizontal path, and applying synchronized compressive rolling pressure adjusted to the width of said wood members to progressively force said tooth extremities into penetrating assembled relation along the length of said wood members.
- 27. A production method for splicing the ends of longitudinal wood members connected by stamped sheet metal elements having toothed extremities fixedly penetrating said wood members comprising the steps of prepositioning said wood members in end abutting relation, positioning said elements on respective horizontally spaced sides of said wood members in required overlapping relation to said abutting ends, driving and guiding said wood members along a horizontal path, and applying synchronized compressive rolling pressure adjusted to the width of said wood members to progressively force said toothed extremities into penetrating assembled relation along the length of said wood members.
