Hi If I remember right that 1/2 inch rubber with the sticky tape on it is used as a spacer for the LCD display. You are supposed to stick it on the pc board under the display and then stick the display to it and then solder the pins. I have not built a K1 lately (although I have built several) so with the new backlight this may not be the way it is mounted now.
