Definitions
- a preferred material comprises fluorescent retroreflective cube corner sheeting, also known in some instances as diamond grade sheeting.
- the sheeting consists generally of prismatic lenses formed in a
- Figure 1 also discloses features of the present invention which permits use of existing motorized roller applicator apparati to provide simultaneous side by side splicing of a plurality of rolls during a lamination process.
- main shaft 20 also provides support for roll 34 of retroreflective cube corner sheeting 16.
- Roll 34 may be of any desired length, however a length of either 12 inches, 24 inches, or 36 inches, or similar normal increments according to local standards, is preferable.
- Axial spacers 40 are positioned along main shaft 20, and are preferably linked to the roll applicator apparatus at the main shaft.
- axial spacers 40 are substantially linked to main shaft 20 by compressed positioning between roll 16 and clamp means 42, which functions as a locking collar type of mechanism.
- Figure 5 depicts a rear view of a portion of apparatus 10.
- Figure 5 illustrates that differently sized rolls may be used in combination with this invention to create side by side spliced retroreflective cube corner sheeting. This feature is shown by comparing the length LI of roll 14 and length L2 of roll 34.
- Figure 5 also depicts use of brake arm 50 in one or more locations along a spindle 54. Shim rudder 66 is shown as an optional feature in this depiction.
- shim rudder 66 is depicted in use positioned between sheeting 16 to provide precise separation between the adjacent sheetings. It is also noted in Figure 6 that sheeting 16 from each roll is of equal length L3.
- main shaft 103 rotates at a desired speed, and is controlled using tensioned movement as determined by brake adjustment mechanism 116.
- Main shaft 103 traverse adjustment mechanism 118 is also provided.
- Axial spacer 40 is optionally used along with clamp means 42, which may comprise a tapered collar or spool clamp of various sizes or shapes. In essence, it is only necessary to fix the axial location of roll 107 with whatever means necessary and convenient.
- Auxiliary shaft 110, and related components preferably comprise a subsystem mounting bracket 122 (shown in this embodiment as an angled base) , a spindle or shaft bearing 124 which acts as a thrust bearing mechanism to regulate axial movement of the shaft, a brake mechanism 128, and a snap collar mechanism 131.
