Claims
- 1. In apparatus for making different siding using a series of spaced stations each having cooperating pairs of opposed upper and lower rollers arranged at spaced intervals and supported for rotary movement to form a selected shape in the sheet material and including a rotary punch at a selected of said stations, said rotary punch comprising:
- a first roller portion having a plurality of circumferentially spaced and radially projecting punch members, each punch member having a pair of spaced punch teeth that substantially simultaneously engage the material as said first roller portion is rotated and punch through the sheet material to form a punched out slug, said spaced punch teeth of each punch member being circumferentially spaced on said first roller portion so as to form two longitudinally spaced shearing points in said sheet material during initial engagement with said sheet material as said sheet material is fed therethrough
- a second roller portion opposite said first roller portion with a circumferential slot that receives a punch member during punching, said circumferential slot being defined by a pair of annular side walls connected by a bottom wall, the bottom wall defining an internal diameter on said second roll portion, a substantially continuous floating ring surrounding the bottom wall of said circumferential slot and slidably supported in said slot, the internal diameter of said slot being less than the internal diameter of said floating ring so said ring will move up and down in said slot as said first and second roller portions rotate and push said slug away, said first and second roller portions being rotated for forming a series of spaced holes along an edge of the sheet material to form a one piece nail strip siding.
- 2. In apparatus as set forth in claim 1 wherein each punch blade is of a generally rectangular shape with a curved surface at one end, there being a leading tooth along one side and a trailing tooth along the opposite side in spaced relation to said leading tooth, said leading tooth being shorter than said trailing tooth in an outward radial direction with respect to the axis of said first roller portion so said teeth will engage the sheet material at substantially the same time.
- 3. In apparatus as set forth in claim 1 wherein said first roller portion is axially movable and including lateral adjustment means to lock said first roller portion at different axial positions to form either a one piece or two piece nail strip siding.
- 4. A rotary punch for use at a selected station in a roll forming machine through which sheet material is passed comprising:
- a first roller portion having a plurality of circumferentially spaced and radially projecting punch members, each punch member having a pair of spaced punch teeth that substantially simultaneously engage the material as said first roller portion is rotated and punch through the sheet material to form a punched out slug, said spaced punch teeth of each punch member being circumferentially spaced so as to form two longitudinally spaced shearing points in said sheet material during initial engagement with said sheet material as said sheet material is fed therethrough,
- a second roller portion opposite said first roller portion with a circumferential slot that receives a punch member during punching, said circumferential slot being defined by a pair of annular side walls connected by a bottom wall, the bottom wall defining an internal diameter on said second roll portion, a substantially continuous floating ring surrounding the bottom wall of said circumferential slot and slidably supported in said slot, the internal diameter of said slot being less than the internal diameter of said floating ring so said ring will move up and down in said slot as said first and second roller portions rotate and push said slug away, said first and second roller portions being rotated for forming a series of spaced holes along an edge of the sheet material to form a one piece nail strip siding.
TECHNICAL FIELD
This application is a division, of application Ser. No. 512,378, filed Apr. 23, 1990, now U.S. Pat. No. 5,038,592, issued Aug. 13, 1991.
This invention relates to a novel and improved apparatus for making shaped panel members and particularly apparatus for making siding of different configurations, different widths, and different edge fastenings using the same machine.
Siding for buildings is commonly used in residential and commercial building construction. This siding has heretofore been made from sheet metal coil stock using roll-forming apparatus. Some of the different configurations or shapes of building siding presently in use are commonly referred to as the colonial, horizontal double four, horizontal double five, vertical board and batten, vertical double four, vertical double five and colonial dutch lap.
Knudson U.S. Pat. No. 3,791,185 discloses apparatus for forming siding for buildings wherein the lower of each pair of a group of pairs of rollers are dropped down so that the same apparatus may be used to form different siding shapes.
Knudson U.S. Pat. No. 4,899,566 discloses pairs of rollers in roll-forming apparatus having lateral adjustments of the rollers in each pair to form shaped panels having different panel widths from the same rollers.
Beymer U.S. Pat. Nos. 3,710,607, 3,788,115, 4,020,666 and 4,787,233 disclose machines for roll forming siding from sheet material using a series of roll-forming stations.
Apparatus for making siding disclosed includes a series of roller stations with each station having opposed pairs of upper and lower rollers between which a sheet material is successively passed. The first station includes a rotary punch with a plurality of circumferentially spaced punch blades on one roller portion and a circumferential slot and a movable ring in the slot on an opposite roller portion which co-operate to form a series of slots in the material for making a nail strip siding. The second optional station has a pair of embossing rollers shaped to provide a wood-like grain in the sheet material so the siding will resemble wood. One of these embossing rollers moves between either a shaping or non-shaping position so that providing the grain is optional. The third through ninth stations form the connecting flanges along opposite side edges. These stations have roller lateral adjustment to form the flanges for two different siding widths. The tenth through nineteenth stations have a lever-cam conversion system which enables selected pairs of opposed rollers to be moved between either a shaping position or a spread non-shaping position which allows the material to pass freely therebetween. The lever-cam conversion system together with roller lateral adjustment forms siding of several different configurations in two different widths.
