Abstract:
A slipform paver including a dowel bar inserter unit having a pair of spaced-apart, endless transport chains oriented transversely to the travel direction. Each chain defines upper and lower strands with turn around chain sections at respective ends of the chain strands. A plurality of pairs of generally L-shaped opposing cups carried by exterior sides of the chain hold the dowel bars so that they can drop downwardly from the cups towards the concrete strip. A dowel bar holding magazine is located above the upwardly facing sides of the chains. Elastic bands having ends fixedly attached to the magazine extend generally about a portion of a convexly curved dowel bar engaging surface defined by a wheel and resiliency bias the dowel bars moving along the chain turn-around section against the wheel.
