what happens to paired reads that do not overlap?

Hi, I understand that in the make.contigs step, paired reads that overlap will be reconstructed to make longer contigs. I am wondering what happen to those reads that do not overlap because the fragments are too long? Are they included in output fasta file or throw away?
Thanks.
