paste with list

Hello,

I guess the solution is rather simple but whatever I tried, I don't manage
to get the result as I want to have it:

I have several vectors of equal length in a list and I'd like to combine all
first elements to a single string, all second elements to a single string,
..., all n-th elements to a single string.

# Example code (how it should look like):
t1 <- c(1,2,3)
t2 <- c(3.4,5.5,1.1)
paste(t1,t2, sep="\t")

# and now how the data is available
tl <- list(t1,t2)
??? what do I have to do to get the same output ???

Can anybody help me?
