When the bill contains an application for a temporary injunction a hearing thereon shall be granted within ten (10) days after the filing of the bill; but a copy of the complaint together with a notice of the time and place of the hearing of the application for a temporary injunction, shall be served upon the defendants at least five (5) days before such hearing. If the hearing be then continued at the instance of any defendant, the temporary writ as prayed shall be granted as a matter of course. Each defendant so notified may file a verified answer on or before the date fixed in said notice for said hearing, but the court or judge may allow additional time for so answering, provided such extension of time shall not prevent the issuing of said temporary writ as prayed for. No bond shall be required for the issuance of any restraining order or temporary injunction mentioned in this chapter.
