FR2492225A1 - Machine for trimming the circumference of open tarts or flans - uses annular cutter die brought down by fluid power cylinder - Google Patents

Abstract

A machine for trimming the circumferential edge of an open tart or flan prior to baking. Trimming takes place after the unbaked tart base has been filled and a cover applied over the filling. The machine has a supporting plate on which the tart is positioned coaxially beneath a trimming die. The trimming die is brought down upon the tart by the descending piston rod of a fluid power cylinder. The fluid can be supplied to the cylinder by a pump which may be manually operated or electrically powered. Pref. the die has an annular cutter which trims the circumference of the tart. Pref. the die also presents an impressing ring set coaxially within the cutter and of less height than the cutter. All trimmed tarts are of similar size and appearance. Trimming is easier and quick than when carried out manually. The amount of offcut waste is reduced.

Description

 The object of the invention relates to an apparatus for tart bordering.

 It makes it possible to perform mechanically with perfect regularity, the peripheral lifting bordering the pies.

 To date the pastry pies have been prepared by spreading the filling on a roll which is then covered and the edges of which are manually raised. This manufacturing was long irregular and led to a loss of raw material.

The device according to the invention eliminates the peripheral rr formation, annual, which gives an appreciable gain in terrps, an increased yield while achieving at the same time as a product of regular presentation, a saving of material.
First by recovery of the fallen.

In the accompanying drawings given by way of nonlimiting example of one of the embodiments of the subject of the invention
Figure l shows the device as a whole.

 Figure 2 shows a sectional view of the mobile matrix.

 Figures 3 and 4 show the product obtained.

 The device consists of a frame 1, the base 2 of which supports the fixed plate 3.

 A movable matrix 4 is connected to the rod; a jack 6 controlled either electrically 7 or manually F-.

 The mohile matrix is formed by a circular element @ with peripheral knife disconnector 10.

 This element concentrically contains the border forming part 11 with profile 12, comprising a circular heel 12 whose height is slightly less than the knife 10.

it obviously forms, of course, a peripheral groove whose outer naroi joins the overhanging knife 10.

 The prepared pie, that is to say with the pastry 15, the filling 16 and the covering 17 is placed with its carrier pluteau IS on the fixed part 3 of the device. By lowering the matrix L, the knife 10 cuts the perinhérie of the pie and the tpmbée 20 is recovered.
