Signature hopper with lap straightening device
View Patent ↗A storage vessel for holding between shaves a wet razor with its head and cutting blade submerged in a liquid and its handle held out of the liquid and dry. The vessel liquid is comprised of a mixture of hydrophobic and hygroscopic materials and of anti-viral and anti-bacterial materials, effective to reduce cutting blade oxidation due to exposure to water and air during nonuse storage and to maintain the blade sharp and sanitary for shaving comfort. These materials specifically might be mineral oil and calcium chloride (CaCl 2 ), and nano-gold or nano-silver.
1. A method for retrofitting a saddle stitcher comprising:
retrofitting the saddle stitcher by adding an adjustable arced extension piece to a signature support of a first drum of a hopper for supporting a signature or sheet between the arced extension piece and the first drum of the hopper such that both the signature support and the arced extension piece support and contact the signature as the signature is transported on the first drum.
2. The method for retrofitting a saddle stitcher as recited in claim 1 further comprising the step of adjusting an angle of the arced extension piece with respect to the signature support or first drum.
3. The method for retrofitting a saddle stitcher as recited in claim 1 further comprising the step of adjusting a position of the arced extension piece with respect to the signature support or first drum.
4. The method for retrofitting a saddle stitcher as recited in claim 1 wherein the step of adding an adjustable arced extension piece includes mounting the arced extension piece to the signature support using washers and bolts.
5. The method for retrofitting a saddle stitcher as recited in claim 1 wherein the arced extension piece includes a slot.
6. The method for retrofitting a saddle stitcher as recited in claim 5 wherein the step of adding an adjustable arced extension piece includes passing a fastener through the slot to adjustably secure the arced extension piece to the signature support.
7. The method for retrofitting a saddle stitcher as recited in claim 6 further comprising sliding the extension circumferentially with respect to the first drum to vary the position of the fastener with respect to the slot.
8. The method for retrofitting a saddle stitcher as recited in claim 1 further comprising sliding the arced extension piece along the signature support to adjust an end position of the arced extension piece circumferentially with respect to the first drum.
9. The method for retrofitting a saddle stitcher as recited in claim 1 wherein after the adjustable arced extension piece is added to the signature support the arced extension piece extends circumferentially around the first drum such that the step of adding the adjustable arced extension piece effectively increases the circumferential length of the signature support.
10. The method for retrofitting a saddle stitcher as recited in claim 1 wherein after the adjustable arced extension piece is added to the signature support the arced extension piece and the signature support extend circumferentially around the first drum and are spaced from the first drum by the same distance.
11. The method for retrofitting a saddle stitcher as recited in claim 1 wherein the arced extension piece is added to the signature support between the first drum and a second drum of the saddle stitcher.
12. The method for retrofitting a saddle stitcher as recited in claim 1 further comprising removing a dipper blade and adding a dipper blade with a curved end, the curved end facing away from a direction of rotation of the first drum.
13. The method for retrofitting a saddle stitcher as recited in claim 1 further comprising adding a cam mask to a primary gripper cam controlling closing of a primary gripper on a second drum of the saddle stitcher, the cam mask causing the primary gripper to close more quickly.
14. The method for retrofitting a saddle stitcher as recited in claim 1 further comprising removing a primary gripper on a second drum of the saddle stitcher and adding a curved primary gripper with a curved end to the second drum, the curved end curving in a direction of rotation the second drum.
15. The method for retrofitting a saddle stitcher as recited in claim 1 further comprising adjusting an angle between a register stop and an end of the arced extension piece by sliding the arced extension piece relative to the signature support, the register stop being positioned at a circumference of the first drum.
16. The method for retrofitting a saddle stitcher as recited in claim 1 wherein the arced extension piece is added to the signature support at a position such that the first drum rotates the signature past a first end of the arced extension piece opposite of a second end of the arced extension piece that is adjacent to the signature support.
17. The method for retrofitting a saddle stitcher as recited in claim 16 wherein the arced extension piece is added to the signature support at a position such that as a lead edge of the signature contacts a register stop positioned at a circumference of the first drum a trailing edge of the signature is positioned past the first end of the arced extension piece.
18. The method for retrofitting a saddle stitcher as recited in claim 1 wherein the arced extension piece is added to the signature support at a position such that the extension piece supports a trailing edge of the signature as a gripper on the first drum grips a lead edge of the signature.
19. The method for retrofitting a saddle stitcher as recited in claim 1 wherein the arced extension piece is added to the signature support at a position such that the extension piece extends past the signature support in a direction that the first drum rotates during operation.
