The grammar pattern "~ともなく/〜ともなしに" is used to express doing something without a specific reason or purpose, or without being conscious of it.
It implies that the action is done naturally or unintentionally.
For example, if you say "彼は歩きながら、考え事をするともなく、街を歩いていた" (Kare wa aruki nagara, kangae goto wo suru tomo naku, machi wo aruite ita), it means "He was walking through the town without really thinking about it, lost in his thoughts", indicating that he was walking without a specific purpose or intention, just lost in his thoughts.
