	Letters of Recommendation

		Dear Sirs, Since 1961 we have been using various types of Spiro equipment, and these have proved excellent in every way. We have been pleased with the workmanship of the machines, their performance, and the products.
	In addition we have always found the service for spares and maintenance first class and our relationships throughout this period have been friendly and purposeful. Yours faithfully For Henry Hargreaves and Sons Limited

		Dear Sirs, In 1958 we purchased a Type 401 Spiro Tubeforming Machine which we use for manufacturing spiral lock seam tubes, used in our air conditioning and ventilation installations.
	Since the day of delivery this machine has been in continous operation and it has performed to our entire satisfaction. We are glad to give this machine our very best recommendations to any prospective buyer.

		Dear Sirs, The machine has been in operation for about 6 months, and has been operating with galvanized steel as well as aluminium strip. The tube dimensions produced so far have been from 3.1/2" and up to 24" diameters.
	The machine delivered to us has proved to be very fool-proof in operation, and has kept all of the guaranteed capasities. The changeover of tools for the various dimensions is done very quickly and requires only from 5 to 15 minutes depending on the dimensions. It is a great pleasure for us to be able to inform you that we are very satisfied with the machine, and that we have been able to recommend it to others who have seen it in operation.

		Dear Sirs, It is a pleasure for us to inform you that after the very careful study made by our technical department of your tube manufacturing machine we are convinced that your machine is extremely well suited for our use.
	We are therefore, recommending to our associated companies and distributors who require this type of tubing that they buy your machine exclusively. We know that you will give to all our associates who purchase machines in the future the same best attention you have given those who have already purchased machines. We will be glad to recommend your machine to anyone interested.

		Dear Sirs, We are pleased to inform you about the Spiro Tubeforming Machine which we purchased approx. 2 years ago.
	With regards to easy operation and production capasity the machine has by far surpassed our expectations, and the tubing produced is very satisfactory. We are glad to be able to give your machine our very best recommendation.

		Sehr geehrte Herren! Auf Ihre Anfrage hin bestätigen wir Ihnen gerne, dass die von Ihnen gelieferte Spiro-Maschine zu unserer Zufriedenheit arbeitet. Wir verarbeiten auf der Maschine Platal, einen Verbundwerkstoff aus Kunststoff und Eisen, sowie aluminiumplattiertes, verzinktes und blankes Band.
	Die Spiro-Maschine verformt dieses Bandmaterial einwandfrei zu Spiro-Röhren. Als besondere Vorteile haben sich die einfache Bedienung der Maschine und die relativ kurzen Umstellzeiten beim Übergang von einem auf einen anderen Rohrdurchmesser erwiesen, wobei nur das leicht transportabele Rohrformwerkzeug gewechselt zu werden braucht. Die hohe Ausstossgeschwindigkeit der Maschine und das Fahren sämtlicher Rohrdurchmesser aus einer Bandbreite und damit ohne ein Wechseln des Bandes ermöglichen es, vielseitige Fertigungsprogramme schnell zu erledigen. Die von uns eingesetzte Spiro-Maschine arbeitet präzise und störungsfrei.

		Gentlemen: Thought you would be interested in the November issue of our Power Plant showing the Spiro Tubeformer.
	We are very happy with the performance of this machine and are forming tubes of many sizes and materials.

		Messieurs, Depuis l'année 1960, nous avons successivement commandé à votre Société: une machine SPIRO 600, une machine SPIRO 600S, une machine SPIRO 800C, une machine SPIRO DUCT FORMER, une machine SPIRO 700N.
	Nous sommes entièrement satisfaits tant sur le plan de la robustesse, de la capacité de production, de la rapidité d'éxecution, que de la qualité des gaines produites sur ces machines. Ces différentes raisons vont motiver, de notre part, nous sommes heureux de vous en informer, l'achat d'une nouvelle machine SPIRO 700N que nous sommes demanderons comme à l'accoutamée de nous livrer avec les mêmes soins que ceux ausquels vous nous avez habitués depuis 15 ans. Nous vous prions d'agréer, Messieurs, l'expression de nos sentiments distingués.

		Dear Sirs, We have now had the latest Spiro machine in production for several months and we have no complaints at all.
	The machine is working extremely well and what pleases me most is that the change-over is very small indeed.

		Dear Sirs, We would advise, in answer to your recent enquiries in connection with the operation of our Type 403, Spiral Conduit Machine, that we have found the production of the conduit to our satisfaction.
	And to-date, the machine has operated very successfully.
