ROW INT,
TEZGAH VARCHAR(50),
COZGU VARCHAR(50),

FIRE INT,
FIRE_METRE NUMERIC(25,6)

from cozgu_fırelerı
where tezgah = 'M01' and cozgu = 'SAĞ ALT BAĞLANTI'
SELECT T1.TEZGAH, T1.COZGU, T1.PERSONEL,T1.FIRE, T1.FIRE_METRE, t1.DATE, T2.DATE AS PREVIOUSDATE, ISNULL(DATEDIFF(DAY, T2.DATE, T1.DATE), 0) AS GUNFARKI , SUM(MKARE) AS TOPLAMMKARE
FROM #TEMPCOZGU as t1
left outer join #TEMPCOZGU as t2 on t1.row-1 = t2.row
left outer join HALI_TEZGAH AS TE ON T1.TEZGAH = TE.TEZGAH_NO
LEFT OUTER JOIN HALI_GUNLUK_URETIM AS U ON U.TEZGAH = TE.ID
--WHERE U.TARIH BETWEEN T1.TARIH AND T2.TARIH
GROUP BY T1.TEZGAH, T1.COZGU, T1.PERSONEL, T1.DATE,T1.FIRE, T1.FIRE_METRE, T2.DATE

If the datetime values always have the time set to "00:00:00", try
SELECT T1.TEZGAH, T1.COZGU, T1.PERSONEL,T1.FIRE, T1.FIRE_METRE, t1.DATE, T2.DATE AS PREVIOUSDATE, ISNULL(DATEDIFF(DAY, T2.DATE, T1.DATE), 0) AS GUNFARKI , SUM(MKARE) AS TOPLAMMKARE
FROM #TEMPCOZGU as t1
left outer join #TEMPCOZGU as t2 on t1.row-1 = t2.row
left outer join HALI_TEZGAH AS TE ON T1.TEZGAH = TE.TEZGAH_NO
LEFT OUTER JOIN HALI_GUNLUK_URETIM AS U ON U.TEZGAH = TE.ID
WHERE U.TARIH >= T1.TARIH AND U.TARIH < DateADD (T2.TARIH, INTERVAL 1 DAY)
GROUP BY T1.TEZGAH, T1.COZGU, T1.PERSONEL, T1.DATE,T1.FIRE, T1.FIRE_METRE, T2.DATE
If that's not the case, then your between should have worked in the first place.
