the splice applied only on one side allows the splice applied only on one side allows thinner splices but the adhesive could get thinner splices but the adhesive could get through the two edges of paper and sticks to through the two edges of paper and sticks to the layer below the layer below


applying two tapes (one per side) you avoid applying two tapes (one per side) you avoid this issue and for reducing the thickness you this issue and for reducing the thickness you could use tapes of different widths and/or shift could use tapes of different widths and/or shift them to each otherthem to each other


compared to overlap splices, butt splices compared to overlap splices, butt splices usually allow the splice to be thinnerusually allow the splice to be thinner

a thin splice is important because it has to a thin splice is important because it has to pass through narrow gaps of the producing or pass through narrow gaps of the producing or converting machines (for example the gap converting machines (for example the gap between calender rolls)between calender rolls)
