BONN, NOV. 10 -- Soviet President Mikhail Gorbachev left Germany today after receiving warm words of support for his struggle to reform his collapsing union, but little prospect of more money.

The Soviet leader, who already has won pledges of $10 billion from the Germans for the support of the 600,000 Soviet soldiers and dependents still living in east Germany, sought new credits and support for the transition to a market economy.

During his two-day visit, Gorbachev met with leaders of German political parties, visited a 12th-century cathedral in Speyer, waded through a grateful crowd and had coffee with Helmut Kohl and his wife, Hannelore, at the chancellor's weekend home in Oggersheim.

Gorbachev asked Western companies to invest in his country but conceded that his government has not yet created an atmosphere that would lure foreign investors. German politicians, bankers and industrialists responded with growing pessimism about Gorbachev's chances of success and an increasing reluctance to pour more money into what many see as a Soviet sinkhole.

Although the Soviet Union's dysfunctional distribution system makes many forms of economic help almost pointless, German executives said the coming winter probably would require at least some contributions of food and clothing.

"There must be immediate help" from both German industry and government, said Edzard Reuter, chairman of the massive auto and defense conglomerate Daimler-Benz.

German Foreign Minister Hans-Dietrich Genscher said today that Western nations should band together to keep the Gorbachev government intact. "Stability in the Soviet Union is important for stability in all of Europe and therefore . . . deserves our support," Genscher said after meeting with Gorbachev this morning.

Germany will increase its already large imports of Soviet natural gas, Economics Minister Helmut Haussmann said, and the Germans also are considering buying more Soviet oil. The Soviet Union has huge oil fields in Siberian regions such as Tyumen, but it has only slowly entered the world energy market in the current reform period.

Western business leaders, when confronted by the picture of a collapsing Soviet federation, say that even if they wanted to make trading deals, they would not know with whom to sign: Moscow or the various republics. All but one of the 15 Soviet republics have declared economic sovereignty or independence.

Gorbachev heard a far more pleasant message from the thousands of Germans who crowded into the streets of the Rhine town of Speyer. The Soviet leader visited the Romanesque cathedral and his wife, Raisa, played the church organ before the couple joined Kohl in a traditional Palatinate lunch of meat cooked in a pig's stomach, marrow and liver dumplings, fried sausage and sauerkraut.

Some of those in a crowd at Kohl's home urged Gorbachev to pass on the heavy meal, but Kohl dismissed their message that the food was unhealthy, saying, "That may be so, but it tastes good."

Gorbachev also met with leaders of the opposition Social Democratic Party, including Kohl's opponent in the Dec. 2 elections, Oskar Lafontaine. Social Democratic chairman Hans-Jochen Vogel said Gorbachev told him that all chances of a peaceful solution to the crisis in the Persian Gulf ought to be exhausted, but that an eventual military action could not be ruled out.
