Description: |
| This is the Canadian equivalent of US patent 272,316, and both these patents relate to the marking of "coursing lines" on the shingles while they are being sawn. Coursing lines are used to maintain a consistent row spacing when the shingles are being fastened to a roof or other surface. |
