When a motion to correct errors is supported by affidavits, notice of the filing thereof shall be served upon the opposing party, or his attorneys of record, within ten [10] days after the filing thereof, and the opposing party shall have twenty [20] days after such service to file counter-affidavits; reply affidavits may be filed within ten [10] days after filing of counter-affidavits, which periods may be extended within the discretion of the court for good cause shown. Such affidavits shall be considered as evidence without the introduction thereof on the hearing on the motion, and shall be a part of the record without a bill of exceptions. If, besides the affidavits, additional evidence is received, the trial court shall cause the court reporter to record all such evidence, and when so transcribed, the same shall be submitted to the judge, who shall certify that it is a true and complete transcript of such evidence, and the same shall be filed with the court and be a part of the record on appeal without being incorporated into any bill of exceptions.
