Claims29
A method of forming an inner wall of a sidewall configuration of a trailer, said method comprising the steps of:
- a) providing a plurality of posts, each post having slots provided therethrough;
- b) providing at least one pre-configured punching die;
- c) providing a one-piece continuous liner;
- d) securing said one-piece continuous liner to said plurality of posts;
- and
- e) punching slots through said one-piece continuous liner with said at least one pre-configured punching die,
- wherein step (d) can be performed either before or after step (e), and
- wherein one of the plurality of posts and the one-piece continuous liner includes guide openings for engagement with corresponding guide pins on said preconfigured punching die, said guide openings positioned above and below the slots of the respective one of the plurality of the posts and the one-piece continuous liner wherein each guide opening defines a first shape, and wherein a second shape of each slot of the respective one of the plurality of the posts and the one-piece continuous liner is different than the first shape of each guide opening.
A method of forming an inner wall of a sidewall configuration of a trailer, said method comprising the steps of:
- a) providing a plurality of posts, each post having slots provided therethrough;
- b) providing at least one pre-configured punching die;
- c) providing a one-piece continuous liner;
- d) positioning said one piece continuous liner against said posts
- e) securing said one piece continuous liner to said plurality of posts;
- and
- f) punching slots through said one-piece continuous liner with said at least one pre-configured punching die while said one-piece continuous liner is positioned against said posts,
- wherein step (e) can be performed either before or after step (f),
- wherein each post is a monolithic, unitary member spaced-apart from each adjacent post, and wherein each post includes a single, planar surface configured to engage the liner, and
- wherein step (e) includes securing the one-piece continuous liner to the single, planar surface of each post.

- b) providing at least one pre-configured punching die;
- c) providing a one-piece continuous liner;
- d) positioning said one piece continuous liner against said posts
- e) securing said one piece continuous liner to said plurality of posts;
- and
- f) punching slots through said one-piece continuous liner with said at least one pre-configured punching die while said one-piece continuous liner is positioned against said posts,
- wherein step (e) can be performed either before or after step (f),
- wherein step (f) includes positioning the pre-configured punching die adjacent another one of the plurality of posts after the punching.
